REPRINTED FROM VAN NOSTRAND'S MAGAZINE. i $8^ NEW YORK : D. VAN NOSTKAND COMPANY, PUBLISHERS, 23 MURRAY AND 27 WARREN STREETS. 1883. 339- PREFACE. THE usefulness of such tables as are presented in the following pages requires no demonstration in a preface. A glance at the explanatory text and tabular ar- rangement of the values will be sufficient to convince the practical engineer, who has ever had occasion to apply Kutter's formula, that the present collection is in an eminent degree of the labor saving kind. EDITOR OF MAGAZINE. Hydraulic Tables Based on Kntter's Formula. THE tables given below are intended to facilitate the calculation of velocities, discharges, slopes and dimensions of sewers and other conduits, and their use will effect a great saving of time ; as, for instance, instead of calculating the ve- locity and discharge by the use of a troublesome formula, the same result, practically, will be arrived at by taking the product of two factors given in the tables. Kutter's formula is a complicateu equa- tion, and in its general form is : v= c*/r~s in which In this and the following formulae, 6 v=mean velocity in feet per second. c= coefficient of mean velocity. s~ fall of water surface (h) in any dis- tance (/) divided by that distance = h . -y = sme oi slope. I/ r= hydraulic mean depth=area of cross section of water divided by wetted a perimeter= . P d= diameter of circular channel. a = area of cross section of water. p= wetted perimeter. Q= discharge in cubic feet per second. n=ihe natural coefficient depending on the nature of the bed, that is, the lining of the channel over which the water flows, which throughout this article, and in the preparation of the tables, has been taken at .015. Mr. J. C. Trautwine, in his Engineers Pocket Book, states that, " In considera- tion of the rough character of sewer brickwork generally," he has taken n = .015 in Kutter's formula when he calcu- lated the velocities in sewers. Mr. R. Hering, in a paper read before the American Society of Civil Engineers in 1878 on the velocity and discharge of sewers, gave : "^ = .015 " for "foul and slightly tuber- culated iron ; cement and terra cotta pipes with imperfect joints, and in bad order ; well dressed stonework and sec- ond-class brickwork." The tables do not apply to channels with smooth or plas- tered surfaces. They are intended to apply only to sewers, conduits and other -channels whose surfaces exposed to the flow of water are of second-class brick- work, or have surfaces of other material equally rough, such, for instance, as those given above from Mr. Hering's paper. The general form of Kutter's formula is : v c^/^s.c^X^/T . . . (1). from which " (3). 8 2 ac^/r r X<\/7 . . . (5). from which =- ....... (6). V ac^/r The values of c^/7 and ac^/7 for 173 diameters are given in Table 1, and the values of /^/~for 1072 slopes are given in Table 2. It will then be seen that a large range of channels numbering 185456 are included in these tables. The velocity is found by the product of two factors c^/r* and /y/7 and in a similar way the dis- charge is found by the product of the two factors ac^/r~and ^/sT In Kutter's formula given above the value of c is found from an equation in- 9 volving the value of r y n and s, so that any change in the value of s would cause a change in the value of c, but as the influence of s on the value of c is not very marked in such slopes as are usually adopted for sewers and conduits, the value of the coefficient has been calculated for one slope, that of 1 in 1000 or s .001. This value of the coefficient is practically constant for all values of s with a steeper slope than 1 in 1000, and as sewers are generally designed with steeper slopes than 1 in 1000, the tables are well adapted to facilitate the calculations. For flatter slopes than 1 in 1000 up to even 2 feet per mile, or 1 in 2640, the tables give results showing a maximum error in the case of a sewer 2 feet in diameter of less than 2 per cent., and in the case of a sewer 8 feet in diameter less than per cent. ; therefore, for all practical purposes, the tables are sufficiently accurate. The hydraulic mean depth of a cylin- drical conduit flowing full is equal to one- fourth of the diameter. The mean velocity in circular sewers 10 and conduits is the same when running half full as when running full. APPLICATION AND USE OF THE TABLES. To find the mean velocity in feet per second and the discharge in cubic feet per second. Example 1. A circular brick sewer has a diameter of 3 feet and a fall of 1 in 500. What is its mean velocity in feet per second and also its discharge in cubic feet per second ? By formula (l) v~c^/r' X ^/'s7 In column 4 of table 1 and opposite 3 feet diameter the value of c^/r~ is found equal to 80.77, and in table 2 opposite 1 in 500 the value of ^/s~ is found equal to .044721 ; substituting these values in equa- tion, we have : = 3.61 feet per second the mean ve- locity. By formula (5) Q,=av=a X 3.61, but by table 2 the area of a sewer 3 feet in diam- eter =7.06 8 ; substitute this value in equa- tion and OTf T II Q=7.068X3.61 = 25.52, the discharge in cubic feet per second. Again, as a check, By formula (5) Q=ac^F X ^/7. In column 4 of table 1, and opposite 3 feet diameter the value of ac^/f is given as 570.9, substituting this value and also the value of ^/^ as found above, in equa- tion we have Q=570.9X.044721 = 25.53 . cubic feet per second the discharge, which is the same as already found above. Example 2. To find the diameter. (d). The grade (s) of a sewer is to be 1 in 480, and its mean velocity (v) 4 feet per second. What is the required diam- eter ? By formula (2). G V r 7= 7 V* In column 3 of table 2 we find for a slope of 1 in 480 that yj" is equal to .045644. Substitute this in equation, and also the value of v already given, and 12 Now look in column 4 of table 1 for the nearest value of c^/7 to this which we find to be 87.15, opposite 3 feet 4 inches in diameter, which is the diameter required. Example 3. To find the grade of Sewer. A sewer 2 feet 6 inches diameter is to have a velocity when running full or half full of not more than 3^ feet a sec- ond. What should its grade be ? v By formula (3) v~ - In column 4 of table 1 find opposite the diameter 2 feet 6 inches that c^/'r is equal to 70.74. Substitute this value and also the value of v already given in equation, and ^/^~= - =.049477. Now look out the nearest the value of ^/s~ to this in column 3 of table 2, which we find to be .04C507, opposite a slope of 1 in 408, which is the required grade. To find the grade of sewer when the grade is not given in Table 2. Example 4. A sewer having a diam- eter of 8 feet is to have a velocity of 13 3i feet per second. What is its required grade? v By formula (3) *JT 7=1. Look out cyr thp value of c^/7 for 8 feet diam- eter in Table 1, and it will be found to be 158.7. Substitute this value and also the value of v already given in equation and On looking for this value of yTin Table 2 it is not to be found, therefore square each side of equation yT=.022054 and we get =.000486379 =2056 ' therefore the is 1 in 2056. To find the diameter (d). Example 5. A sewer is to discharge 9 cubic feet of water per second and its grade is to be 1 in 200. What is its diameter to be ? 14 By formula (7) ac~/r'= -. In the V s third column of Table 2 and opposite 1 in 200 the value of ^/g~ is found to be .070710. Substitute this value and the discharge already given in equation, and Q we have ac^/7 -- 127.28. In column 5 of Table 1, the value of acy9~ nearest to this we find to be 130.58, op- posite to which is the diameter of 1 foot 9 inches, which is the diameter required. To find the grade or slope of sewer, (s). Example. 6. A sewer 6 feet in diam- eter is required to discharge 180 cubic feet of water per second. What should be its slope? By formula (8) v / ~= ~^- In col- aeyr umn 5 of table 1 and opposite 6 feet in diameter the value of ac\/r~is found equal to 3702.3. Substitute this and also the value of Q in equation, and we have 1 80 ' 15 column 4 of Table 2 look out the number- nearest to this, which will be found to be .045621 opposite a slope 1 in 423, there- fore the required grade is 1 in 423. To find diameters in a series of sewers with increasing discharge. Example 7. A circular sewer has for 500 feet in length to discharge 10 cubic feet per second, then for 600 feet more has to discharge 12 cubic feet per second, and again for 700 feet, farther on 15 cubic feet per second. The total fall available is 5 feet. What is the required diameter and fall of each section ? The total length is 1800 feet and 5 /i8oo = -002777 s and By formula (7), ac^r~= In this equation substitute values of Q and s for each section and find the correspond- ing diameters, which will be the diameter required. 16 89 - 7 1 ( diam.2'-0" Now 5=-- /. A=s/, therefore the 6 Fall of first section sl=. 002 777 X500 ............................. = 1.89 ft. Fall of second section=s=.002777 X600 .............................. =1.67 ' Fall of third section=:^=.002777 X700 .......... ,.. = 1.95 " Total fall 5.00ft. We have, therefore, 1st section, diameter 2' 0", fall 1.39 ft. 2d " " 22" " 1.67 " 3d " " 2' 4" " 1.94 " To find velocity and discharge of tra- pezoidal channel. Example 8. A trapezoidal channel lined with brickwork, 6 feet wide at bot- tom and with side slopes of 1 to 1, has 2 17 feet in depth of water and a grade of 1 in 160. What is its velocity and discharge per second ? Area (#)= X2 16 square feet. Wetted primeter ( +6 = 11. 66 feet. /. Hydraulic mean depth In column 3 of Table 1 look out the nearest value of r to this which we find to be 1.375, and corresponding to this we find c^/r equal to 123.5. In Table 2 for a slope of 1 in 160 the value of <\/H is found to be = .079057. Now by formula (l) v = c^/r X ^/7 and " " " (5) Q,=av substitut- ing the values above found of the factors, then v = 123.5 x. 079057 =9.76 feet per second and Q=16+9.76 = 156.2 cubic feet per second, therefore the mean velocity is equal to 9.76 feet per second and the discharge equal to 156.2 cubic feet per second. 18 To find the dimensions of a circular sewer to replace a rectangular brick chan- nel. Example 9. An open brick channel 5 feet wide at bottom, with vertical sides, has a depth of water in floods of 3 feet and a slope of 1 in 520. It is intended to substitute for it a circular sewer whose mean velocity flowing full shall be about ft. per second. What should be the diameter and grade of the new circular sewer flowing full ? In Table 2 the /y/~ for a grade of 1 in 520 = .043853. Area of rectangular channel (a) 5-J-3 = 15 sq. ft. Wetted perimeter (/>) 3+ 5-f-3 = li feet. /. Hydraulic mean depth (r)-^- 1.364. In Table 1 find corres- ponding to this hydraulic mean depth the nearest c^/r^ which is 123.5. By formula (5) Q= a+c \/7+ \/7 'sub- stitute the values found above, of the factors in right hand side of equation, and Q=15X123.5+.043853:=:81.24 cubic feet 19 per second, the discharge from the rec- tangular channel. We have now to find the diameter and grade of a circular sewer to convey this quantity of water with a velocity not greater than 5 feet per second. By formula (6) a substitute values = - =16.248 square feet=area of circular sewer. In column 2 of Table 1 we find the area nearest in value to this =16.499, and the corresponding diameter equal to 4 feet 7 inches, and at the same time find the value of the corresponding ac^/r which is 1796.5. By formula (8) A /*~= - 7= substitute ac^/r values of Q and ac^/r found above and In Table 2 we find the grade corresponding to this equal to 1 in 489, therefore the diameter of circular sewer is 4 feet 7 inches, and the grade 1 in 489. 21 CIRCULAR SEWERS AND CON- DUITS FLOWING FULL.
