PREFACE 
 
 SOME years ago, when the author was located at 
 Denver, Colorado, in the capacity of Chief Engineer 
 of The Denver Union Water Company, he collected 
 a mass of data relating to the Construction and Main- 
 tenance of Continuous Wood-stave Pipe, with a view 
 of getting the matter into tangible shape for publication. 
 
 It may be of interest to note that Denver was the 
 home of this class of pipe and that the entire water 
 supply for that city is obtained through more than one 
 hundred miles of continuous wood-stave pipe, varying 
 in size from 30 inches to 48 inches in diameter. 
 
 While engaged in the preparation of tables indicating 
 the carrying capacities of continuous wood-stave pipe, 
 the author was strongly impressed with the need of 
 special investigation touching this most important factor 
 of pipe design. 
 
 At that time the formula usually employed in design- 
 ing pipe of this character was Kutter's with n = 0.010, 
 although other formulae had also been used, among 
 them being the expression Hr=mF 1 " 73 . 
 
 It was deemed desirable as well as necessary and 
 essential to a more complete understanding of the sub- 
 ject, to compare results of flow-data obtained by several 
 well-established and accepted formulae, upon a com-

 mon basis, the same to apply to sizes of pipe and slopes 
 usually involved in common practice. 
 
 Accordingly, five well-known formulae were selected 
 by means of which the following tabulated values were 
 computed. Five-place logarithms were employed in these 
 computations and as a ready means of comparing re- 
 sults derived from these formulae, the value of c in the 
 expression v=c\/rs, has been determined for each size 
 of pipe and for slopes as indicated in the extended 
 tables. 
 
 It is believed that an inspection of these comparative 
 values will assist in the proper dimensioning of pipe 
 conduits to meet any desired service.

FLOW OF WATER 
 
 FLOW OF WATER IN CLOSED PIPES 
 
 THE flow of water in any channel is subject to the law govern- 
 ing falling bodies, commonly expressed v = -\/2gh', in which 
 v equals the velocity in feet per second, g equals the " accelera- 
 tion of gravity " and h equals the head of water in feet, producing 
 the flow. 
 
 The value of g varies from about 32.0894 feet per second 
 per second, at the equator sea-level, to 32.254 at< the poles. 
 Its value also varies slightly with elevation above sea-level. 
 For all ordinary calculations applying to the United States, 
 the value of g is generally assumed as 32.16 and -\/2g as 8.02. 
 
 If the flow were not retarded by friction, the amount of dis- 
 charge through a closed pipe would be expressed in cubic feet 
 per second by the product of the following three factors: the 
 internal cross-section of the pipe (expressed in square feet), 
 the square root of 2g (equal to 8.02), and the square root of 
 the head of water producing the flow, expressed in feet; that 
 is the vertical distance of the source of supply above the axis 
 of the pipe, measured at the point of discharge. 
 
 Because of the retarding influence of friction, the amount 
 of flow is less than is indicated by the above expression and 
 the amount of the frictional resistance can be expressed by the 
 difference between the observed velocity in feet per second and 
 that indicated by the expression v = \/2gh or 8.02 \/h. In other 
 words, the frictional resistance is equal to the accelerating force. 
 
 The discussions which have led up to our present knowledge 
 of the laws governing the flow of water in channels have been 
 most varied in their conclusions, and though many errors and 
 false results appear, a study of them is of great interest to one 
 who desires thoroughly to analyze the subject of hydraulics. 
 
2 FLOW OF WATER 
 
 Galileo has be?n quoted is "saying that he found it easier 
 to dekTaaue 1h? laws thut govern the motion of the heavenly 
 bodies than those pertaining to the flow of water in channels. 
 It was owing to his ignorance of the laws relating to the flow 
 of water that important proposed river improvements were 
 abandoned. Since that time, to the present day, experiir enters 
 and investigators have been gradually groping their way out of 
 the darkness and ignorance surrounding the laws governing the 
 flow of water until to-day, we are enabled to calculate with 
 reasonable accuracy the amount of water that can be conveyed 
 through open or closed channels, constructed of different ma- 
 terials and subjected to varying conditions of grades and pres- 
 sures. 
 
 In the light of our present knowledge it seen s strange to 
 read that the Romans, who were so observing and thorough in 
 other lines of thought and investigation, disregarded head or 
 pressure in their calculation of flow of liquids in conduits, re- 
 garding only the size of the conduit; and equally strange does 
 it appear that a man so brilliant and original in his work as was 
 Galileo, should contend that the velocity of a stream is depend- 
 ent solely upon the head or slope and entirely independent of 
 the length or distance traveled by the flow. 
 
 It was not until investigators realized that correct results 
 in the determination of stream-flows must depend upon observa- 
 tion of actual conditions and not upon mere theorizing, that a 
 better understanding of the subject was evolved. 
 
 In the year 1775, M. Chezy, a noted French engineer, suggested 
 the formula v = c\/rs, by which to determine the velocity of 
 water flowing in conduits, in which expression, 
 
 v = velocity of flow in feet per second; 
 
 c = a coefficient to be assumed for each case under considera- 
 tion, and is to be determined by experiments under 
 like conditions; 
 
 r = the mean hydraulic radius^ (usually expressed in feet), 
 
 u - i r T , . diameter in feet 
 which for closed pipes = > 
 
 s = slope = height or head in fee fc 
 horizontal length in feet* 
 
FLOW OF WATEK IN CLOSED PIPES 3 
 
 Previous to the time M. Chezy suggested his formula, the 
 roughness of the sides and bottom of the channel had not been 
 considered as producing any retarding influence upon the flow 
 of water. It was believed that the water immediately covering 
 the holes and projections of a rough surface became in itself a 
 smooth surface, over which the flowing water passed without 
 material loss of motion. Experiments demonstrated the falsity 
 of this assumption and it became generally recognized that the 
 ratio of the cross-section of the flowing current to the wetted 
 perimeter should be incorporated in a formula intended to ex- 
 press the velocity of flowing water. 
 
 The Chezy formula*, above indicated, appears to-day in various 
 modified forms and may be used to determine the amount 
 of flows, either in open or closed channels. Probably the best- 
 known modification of this basic formula is that enunciated by 
 two eminent Swiss engineers, E. Ganguillet and W. R. Kutter, 
 and familiarly known as the Kutter formula, which is expressed 
 as follows: 
 
 XVrs, 
 
 VJ I I XN I 
 
 8 I V7 J 
 
 in which v = mesm velocity in feet per second; 
 
 r = mean hydraulic radius, expressed in feet and 
 equals the cross-section of the stream divided by 
 the wetted perimeter in linear feet. The wetted 
 perimeter is the linear measurement of the 
 sides and bottom of the channel in contact with 
 the flow; 
 
 . , , r fall of water surface 
 
 s = slope of the water surf ace = r : r-, : ; 
 
 horizontal length of flow 
 
 n = coefficient of roughness of the sides and bottom 
 of the channel. 
 
 It will be noted that the bracketed portion of the second 
 term of the formula corresponds with the c in the expression 
 
FLOW OF WATER 
 
 From inspection of the Kutter formula, it is evident that 
 the accuracy of the results obtained by its use is dependent 
 upon the value assumed for n. A little deviation in the assumed 
 value of this coefficient will very materially affect the value 
 of c, as is shown below. Let the value of r be assumed as 0.3 
 foot, corresponding to a diameter of 14.4 inches.

 From an inspection of the above tabulated values of n and c, 
 it is apparent that the value of n must be selected with great 
 care; a change of only a unit in the third decimal place will 
 make a marked change in the value of c. 
 
 The values of n have been determined by experimenting with 
 channels made of different materials, possessing varying degrees 
 of roughness. The results of these experiments are given by 
 Kent substantially as follows: 
 
 1. Smooth, well-planed timber, in perfect order and 
 
 alignment 009

 for iron, cement and terra-cotta pipes, well jointed 
 
 and in good condition Oil 
 
 4. Unplaned timber, when perfectly continuous on the 
 
 inside 012 
 
 5. Ashlar masonry and well-laid brickwork; ordinary 
 
 metal and stoneware pipes in good condition but 
 not new; also materials mentioned under item 2, 
 when imperfect or in inferior condition 013 
 
 6. Second-class or rough-faced brickwork; well-dressed 
 
 stonework; foul or slightly tuberculated iron, 
 cement and terra-cotta pipes, with imperfect joints 
 and in bad order; canvas lining on wooden 
 frames 015 
 
 7. Brickwork, ashlar masonry and stoneware, in inferior 
 
 condition; tuberculated iron pipes; rubble in 
 cement, in good condition; fine gravel, or particles 
 ranging from J to f inch in diameter, well rammed, 
 and generally the materials mentioned under item 
 5, when in bad condition 017 
 
 8. Rubble in cement in inferior condition; coarse rubble 
 
 laid dry; brickwork in very poor condition; coarse 
 gravel of particles ranging from 1 to IJ-inch in 
 diameter, well rammed; canals with beds and 
 banks of very firm, regular gravel, carefully trimmed 
 and rammed in defective places; rough rubble 
 with bed partially covered with silt and mud; 
 wooden troughs, with battens on the inside two 
 inches apart; earth trimmed to perfect condition .. .020

 10. Canals and rivers in earth, of tolerably uniform cross- 
 
 section, slope and alignment, in moderately good 
 condition and free from stones and weeds 025

 average conditions 0275

 Information published by the U. S. Geol. Survey indicates 
 a more conservative selection of the value of n than noted above, 
 as for instance materials included under item 5 would be classi- 
 fied by the Government as under item 6, having a value of .015, 
 and so on down the list. It requires the exercise of the keenest 
 judgment, born of long experience, to select the value of n that 
 will give results even roughly approximating the truth. 
 
 Different experimenters will determine different values of n 
 with the same conduit, and the application by another party to 
 another conduit of the results obtained by these experimenters 
 is simply the exercise of the guessing power of that individual. 
 It may or may not approximate the truth. 
 
 Considering the unwieldy and complex expression of the 
 Kutter formula, coupled with the fact that the value of n is 
 so largely a matter of speculation, the author contends that 
 one may as well guess the value of c in the Chezy formula and 
 save his " gray matter"; for in so doing, it is possible to differ- 
 entiate to a greater degree of nicety than can be done in valuing 
 n in the Kutter formula. 
 
 There are so many writings which discuss at length the 
 results of ancient hydraulicians to which the reader can have 
 access, if he desires to make a careful study of them, that it is 
 not deemed expedient to discuss them in this instance, but 
 rather to confine our attention to a few formula of more recent 
 date, which more closely conform to modern practice, the results 
 of many years of experience an advantage which the older 
 hydraulicians did not possess. 
 
 H. D'Arcy, a French engineer of large practical experience, 
 realized the necessity of carefully conducted experiments, in 
 order to deduce satisfactory formulae relating to the flow of 
 water. From his practical knowledge of the subject, he was 
 amply qualified to conduct a series of observations upon the 
 
FLOW OF WATER IN CLOSED PIPES 7 
 
 flow of water in pipes and open channels, that have resulted in 
 giving to engineers most helpful information. 
 
 As a result of experiments, he devised the following formula, 
 which is popularly known as the D'Arcy Formula: 
 
 - - 
 
 \, 
 
 \'rs. 
 
 _ (K)007726+; 00000647 
 
 - 
 
 In which s = slope=-^-; d=internal diameter in feet; r = mean 
 
 hydraulic radius in feet; v = velocity in feet per second. 
 
 If the D'Arcy formula, relating to the flow of water in pipes, 
 as above expressed, is hot more generally employed than any 
 other formula, it is certainly one of the most popular in use, 
 and in the opinion of the author most deservedly so. In an 
 experience of more than thirty years in the design and operation 
 of public water systems, this formula has most satisfactorily 
 aided in solving the many varied problems that have demanded 
 the author's attention. 
 
 It has been thought desirable to reduce the formulae, as ad- 
 vocated by Merriman, Fanning, Gould and D'Arcy, to the 
 simple form of the Chezy formula. These formulae all relate 
 to clean cast-iron pipes. With pipes running full, the Chezy 
 
 formula can be reduced from the form v = c\/rs to v= %/ .

 In general practice the velocity of the water in supply and 
 distribution mains will range from 2 to 5 feet per second. 
 With this fact in view, the values of c, as given in the previous 
 table for each size of pipe and corresponding to velocities of 
 2, 3, 4, and 5 feet, have been added together and average values 
 from the four formulae considered, have thus been obtained. 
 These results have been plotted upon logarithmic paper and a 
 correction line drawn. 
 
 The average values of c as derived from the four formulae, 
 adapted to various-sized pipe and including velocities of 2, 3, 
 4 and 5 feet, are given below, together with the corrected values.

 It should be borne in mind that the formulae irom which these 
 values are obtained contemplate clean cast-iron pipe. Some 
 values derived from Flynn's tables are added, as being of interest:

 It will be observed that all the formulae considered above indicate 
 that the frictional resistance to the flow of water varies as the square 
 of the velocity. 
 
 In a paper presented before the American Society of Civil 
 Engineers in 1902 by Theron A. Noble, on " Flow of Water in 
 Wood Pipes," reference is made to experiments conducted by 
 Mr. Noble, as well as by Mr. Arthur L. Adams and others. In 
 discussing this paper, Mr. E. W. Schoder shows that the results 
 of the experiments noted indicate that the loss of head or fric- 
 tional resistance " varies about as the 1.73 power of the velocity," 
 instead of as the square of the velocity, as assumed in most of 
 the formulae extant and in general use. 
 
10 FLOW OF WATER 
 
 Mr. Schoder, in discussing this paper, makes use of the formula 
 Hf=mv n , in which /// represents the loss of head or frictional 
 resistance per unit of distance, and v the velocity in feet per 
 second, n being a coefficient, which varies with each size of pipe. 
 
 This form of expression is probably as simple as can be devised 
 for showing the relation existing between velocity and loss of 
 head in pipes conveying water under pressure. Assuming H 
 to represent the loss of head per 1000 feet for clean cast-iron pipe, 
 and to vary as the square of the velocity, it ^ ill be interesting 
 to determine the value of m for each- size of pipe, first, when 
 c in the Chezy formula has a constant value of 100 for all sizes 
 of pipe; second, when c varies with the size of the pipe, as de- 
 termined by averaging results obtained from formulae advocated 
 by Merriman, Fanning, Gould and D'Arcy, as heretofore ex- 
 plained; and third, when c has the values detern ined by the 
 D'Arcy formula, which values are constant for all velocities, 
 for any particular size of pipe, but vary with the size of the pipe. 
 
 It is evident that m equals H when v equals 1 foot rer second; 
 hence, the values of m in the expression H/=mv n rray be de- 
 termined by assuming v to equal unity. The values of m have 
 thus been determined, subject to the assumptions above noted 
 and are given in Table 2. 
 
 Frictional resistance varies very nearly as the square of the 
 velocity and inversely as the product of cV, as indicated in the 
 
 v 2 4v z 
 
 expression, slope = = . 
 c 2 r c 2 d 
 
 If the value of c were constant for all values of d, it is apparent 
 that the frictional resistance for like velocities would vary in- 
 versely with the diameter, but such is not the case if c varies 
 with the diameter. 
 
 Both theory and practice are essential to a well-grounded 
 understanding of the principles required by the hydraulic 
 engineer, but the practical man needs to be continually on his 
 guard against being misled by a class of technical writers who 
 are disposed to treat engineering as an exact science, whereas 
 it is so only in name. Unpracticed and inexperienced in build- 
 ing and maintaining engineering works, many of these writers 
 consider only the theoretical side of a problem.

 This class of writers reminds the author of a young engineer, 
 bright and particularly apt in all mathematical work, but who 
 was so exact in his ideas that he did not know when to drop 
 excessive refinement and exercise good common sense. In 
 cross-sectioning for earth-work stakes, he would try to set the 
 stakes to a thousandth of a foot. Had the rodman pressed a 
 pound weight upon the rod, his calculation would have been for 
 naught. As it was, the result was vexation for the rodman and 
 unwarrantable slowness in the work; for that reason this par- 
 ticular engineer was kept employed upon office calculations.

 FLOW OF WATER 
 
 Attention has already been called to the fact that some exper- 
 imenters claim that the resistance to flow in a closed pipe 
 does not vary as the square of the velocity. Professor Gardner 
 S. Williams, in discussing Mr. Noble's paper, referred to above, 
 states that " in 1808 Dr. Thomas Young suggested, in an address 
 before the Royal Society, that the exponent of the term indicat- 
 ing the velocity was more nearly 1.8. Later, in 1855, Thomas 
 Hawksley made an extended exposition of the same view, and 
 in 1873 Mr. Lampe presented the results of his experiments on 
 the Danzig pipe line as expressed by his well-known formula 
 v = 203.3 r- 694 $- 555 
 
 = 77.63 d- 694 s- 555 , 
 r = the mean hydraulic radius,

 Below are given the results of a number of experiments 
 which are interesting to study. (See Trans. Am. Soc. C.E.,

 An inspection of the above-recorded results indicates how 
 indeterminate and uncertain is the value of the exponent of v. 
 It seems to be materially affected by the condition of roughness 
 
FLOW OF WATER IN CLOSED PIPES 13 
 
 of the interior walls of the pipe, and hence the character of the 
 material forming the pipe is an essential factor. 
 
 Especial attention is drawn to the different results obtained 
 by the same experimenters of the 72^-inch pipe at Ogden, Utah. 
 In 1897 the experimenters ascertained the value of the exponent 
 n to be 1.73, whereas two years later it was found by the same 
 experimenters to be 1.94. Was this difference due to errors of 
 observation or to the changed condition of the internal walls 
 of the pipe? 
 
 While it may be of much interest to a class of investigators 
 and technical writers to determine to a " hair-splitting " degree 
 the exact value of the exponent of v, and though there seems 
 to be good reason for believing that n approximates 1.73, with 
 pipe in good smooth condition, yet the practical man may 
 rightly hesitate to follow any but an absolutely safe course, and 
 provide in his design for a " factor of ignorance," for he is 
 dealing with conditions and materials that are uncertain to a 
 pronounced degree, and instead of " driving too close to the preci- 
 pice," he will do well to be guided by Pat, who affirmed that 
 " Bedad he would kape as far from the hole as possible." In 
 saying this, we do not want to be understood as countenancing 
 ill-advised caution, resulting in needless expense. Reason 
 and good judgment, in other words, the exercise of good common 
 sense must be the guide and safeguard of the practical engineer. 
 
 An engineer rarely gets credit for work well done. When .his 
 estimates of cost and capacity are verified by results, it is only 
 what should be expected and but little, if any, note is made of 
 the fact, but let the capacity of a pipe line fall even a little 
 below the engineer's estimate and that engineer will never 
 outlive the- criticism and censure that his mistake will surely 
 arouse. In view of this and the uncertain, varying conditions 
 attaching to materials and other factors which, in greater or 
 less degree affect every piece of engineering construction, it 
 behooves the engineer to avoid hewing too closely to the line 
 in planning his work. Usually the difference in cost between 
 success and failure is small. It is far better for all interests 
 concerned to incur the additional expense and secure successful 
 results.

 PLOTTING FLOW DATA BY MEANS OF LOGARITHMS 
 
 Everybody who has to make many computations and esti- 
 mates, as is the case with engineers, appreciates the great saving 
 in " gray matter," as well as in time and book space, that can 
 be effected by employing logarithms. Let the reader not 
 drop the benefit of logarithms after he has completed his cal- 
 culations, but let him satisfy himseK that he cannot with profit 
 employ them in plotting his results. In the author's opinion 
 there is no better way to fix a mathematical truth in one's mind 
 than by the use of a diagram. If the reader has not already 
 done so, he is advised to read and carefully study the excellent 
 and practical book entitled " Calculus for Engineers," by John 
 Perry. By means of plots and diagrams, Prof. Perry teaches 
 in a clear, practical and intensely interesting manner, the prin- 
 ciples underlying the calculus and their adaptation to Applied 
 Mechanics. 
 
 Though it may seem elementary and out of place to insert 
 here a brief explanation relating to the application of logarithms 
 to plotting flow data, it is believed that such an explanation 
 may be of assistance to some readers who may not have given 
 the subject special thought. If we desire to plot the expression 
 H=mx, we draw a straight line 0-7 (Diagram A), having a 
 slope of m vertical to one horizontal. The ordinate (vertical 
 distance above horizontal line through 0) opposite to any 
 point in the line will be m times the abscissa (horizontal dis- 
 tance from vertical line through 0) of that point. If instead of 
 H = mx, we wish to plot H = b -\-rnx, we draw a line parallel 
 with the previous one but through a point vertically above 
 and b distance from it. 
 
 To use a concrete case, suppose we wish to plot H=2x, the 
 line 0-7 (Diagram A) serves as the multiplier 2. 
 
 If we wish to plot H = W-}-2x, we draw our line parallel with 
 0-7, but through the point 10. If z =4, then H = 18. 
 
 If on the other hand, we wish to plot H=x m , we can with 
 profit use logarithms. Instead of spacing our lines as in Dia- 
 gram A, proportional to the numbers, we now space them pro- 
 portional to the logarithms of the numbers, as in Diagram B. 
 
PLOTTING DATA BY MEANS OF LOGARITHMS 15 
 
 If now we draw the line 1-7 in Diagram B, with the same slope 
 (m vertical to one horizontal) as 0-7 in Diagram A, the ordinate 
 opposite to any point in the line will be the m power of the 
 abscissa of that point, or H=x m . If we draw our line parallel

 with 1--7 but above it, passing through a point vertically over 
 1 and 6 distance from it, our line represents the expression 
 H=bx m . 
 
 Let z = 1.5 and 6=2, then # = 2-1.5 2 and we read directly 
 from the ordinate of the point in this line, vertically over 1.5 
 and obtain # = 4.5.

 The difference between the two diagrams is, that in Diagram A 
 we space the lines proportional with the numbers and hence 
 obtain simple multiplication, but to multiply a logarithm is to 
 obtain the logarithm of a power of the corresponding number, 
 
 25 
 
 hence the line 1-7 in Diagram B, by multiplying the logarithm, 
 correspondingly raises the number to the m power. Diagram A 
 deals with the numbers, Diagram B deals with the logarithms, 
 hence it is that the line 2-6, in Diagram B, represents the 
 general expression H =bx m instead of H =b+mx, as in Diagram 
 
PLOTTING DATA BY MEANS OF LOGARITHMS 17 
 
 A, because H is made up of the log b plus the log x, and the sum 
 of these indicates a product. 
 
 If any function of a formula varies as a power of another 
 function, the relation between the two can be expressed by a

 VELOCITY m FEET PER SECOND 
 
 straight line, through the use of logarithms; not only this, but 
 if we have the results of any set of experiments, giving the loss 
 of head corresponding to two or more rates of flow, we can readily 
 determine a formula to meet the conditions by means of a loga- 
 rithmic plotting of the results. For instance, suppose we find 
 
18 FLOW OF WATER 
 
 by experiment that the loss of head per 1000 feet in a 24-inch 
 pipe line amounts to 0.620 foot, the velocity of flow being 
 2 feet per ^second, and with the same pipe line, the loss of head 
 per 1000 feet amounts to 0.35 foot at a velocity of 1.5 foot per 
 second and 0.155 foot when the velocity of flow is but 1 foot 
 per second. We desire to find the relationship existing between 
 the velocity and loss of head. 
 
 Plotting the losses of head as shown, upon Diagram C, and 
 connecting the three points, we obtain the straight line ACEB. 
 It will be noted that the horizontal and vertical spacing of 
 the lines is not in proportion to the numbers, tut instead, 
 spacing is in proportion to the logarithms of the mm bers. 
 
 The natural tangent of the angle ECD, which the plotted 
 line makes with the horizontal, represents the pouer of the 
 velocity in the general expression Hf = mv n . The tangent in 
 this case equals 2; in other words the slope of the line is two 
 vertical to one horizontal. This means that the vertical reach 
 or distance of any point in the line, as E } above any other point 
 in that line, as for instance C, is twice the horizontal distance 
 of the same point E from the point C, but to double the logarithm 
 of a number gives the logarithm of the square of that number, 
 hence the ordinate opposite any point in the line indicates the 
 square of the value attaching to that point. In this case then, 
 the loss of head varies as the square of the velocity. 
 
 Let us take another case of a 24-inch pipe line and assume 
 that the loss of head per 1000 feet, at velocity of flow of 2 feet 
 per second, amounts to 0.60 foot; and that the loss of head 
 amounts to 0.40 foot per 1000 feet when the flow has a velocity 
 of 1.6 foot per second, while at velocity of 1 foot the loss of 
 head is 0.18 foot per 1000 feet. If we plot a line through the 
 points indicating these conditions, upon Diagram C, it will be 
 found that the natural tangent of the angle which this new line 
 would make with the horizontal lines upon the diagram is 1.73, 
 indicating that the loss of head, in this case, varies as the 1.73 
 power of the velocity, instead of as the square, as in the first case. 
 
 When the velocity equals 1 foot per second, it is evident 
 that Hf=m. In the first case assumed, m equals 0.155 foot 
 and in the second case its value is 0.20. In this way the

 inspection of Diagram D, upon which are graphically shown 
 values of c, in the expression v = c\/rs, as determined by the sev- 
 eral formulas under consideration and for stated sizes of pipe, 
 when # = 4.0 feet per second. 
 
 Results determined by the Fanning formula for pipes between 
 60 and 96 inches in diameter do not appear to be consistent 
 with the results obtained from the formula for sizes below 60 
 inches in diameter, as shown upon Diagram D. 
 
 It is believed that the values of c for 96-inch pipe by the 
 Fanning formula can stand inspection, but the values for 66, 72, 
 78, 84 and 90-inch pipe are too small, as will be evident by 
 inspecting the Fanning curve on Diagram D. 
 
 It is well known that, under ordinary conditions, the carrying 
 capacity of iron pipe begins to decrease as soon as laid and put 
 into service; just how much this decrease will amount to in 
 stated periods of time is entirely dependent upon local conditions. 
 
 Some writers have undertaken to tabulate percentages of 
 normal or original carrying capacity that pipes will discharge 
 after stated periods of service. To do this seems to the author 
 akin to buying eye-glasses from a curbstone vendor it would 
 
22 FLOW OF WATER 
 
 be a miracle if such glasses chanced to fit the purchaser's eyes. 
 Last year (1914) the author had occasion to test the carrying 
 capacities of two 36-inch parallel cast-iron pipe lines which 
 were laid at the same time (1889), within a few feet of each other, 
 practically in the same trench of same length. With these 
 conditions being the same with both pipe lines, it might be 
 assumed that the two lines would have the same resistance head, 
 and yet, as a matter of fact, one line offered twice as much 
 resistance as did the other. 
 
 Thinking there might be some obstruction causing the larger 
 resistance head, the pipe was uncovered at points 100 feet apart 
 and corporation cocks inserted, to which tested gauges were 
 attached. The resulting pressures, when plotted and adjusted 
 to a common datum of levels, demonstrated that the^resistance 
 was uniform throughout the length of the pipe. At that time 
 the two lines of pipe were delivering water from the same pump 
 and into the same basin. 
 
 The explanation seems to lie in the fact that the pipe line 
 offering the least resistance had previously been used to con- 
 vey raw water from the Missouri River, which carries in suspen- 
 sion considerable sand, and this has contributed in keeping 
 the interior walls of the pipe well scoured and hence free from 
 tuberculation, whereas the other line has been used in carrying 
 water that had been settled and also treated and hence was 
 clear and had no such scouring influence. 
 
 Every pipe line will have to be judged in the light of local 
 conditions. To undertake to prescribe hard and fast values 
 expressing the decrease in carrying capacities, because of age, 
 is, the author believes, a dangerous procedure and is more than 
 likely liable to mislead. Better let each case be decided inde- 
 pendent of others. 
 
 The following table is appended, as a mere suggestion of the 
 effects of age upon cast-iron pipe. The data contained in the 
 table are based upon results of measurements of flow and pres- 
 sures in the pipe-distribution system of a Western city, using 
 filtered mountain water, containing about 30 grains of mineral 
 salts per gallon.
