Laboratory Date Issued, January 1, 1922 tº reas: ... * ** * EQUATION OF PIPES There are published three general types of tables used in comparing the relative capacities of pipe for various diameters and lengths. The first of these is based on formulae in which * the flow is proportional to -------- yº DT Applied to the actual diameter this base equation re- sults in a table such as is given in Kent's Handbook. While such tables may be of occasional interest, they are of little practical use, for the reason that the nominal diameters of gas pipes are not the same as the . actual diameters. The second type of table is derived by applying the base equation given, above to actual inside diameters, the tables being compiled by arranging values accord- ing to the nominal size, either alone or together with the corresponding actual inside. diameters. The tables. given in the Handbook of the National Tube Company. are based on this method. Such tables are commonly used but can be considered only approximately cor- . . . rect; since they do not involve changes in coefficients, - due to different velocities, etc. . . - - - - - … . . . . The third type of table is obtained from the work of J. M. Spitzglass. His formulae are based on the experimental result and so far as they go, probably give more accurate values than those considered under the second group. -- - - The values appearing in the P. C. G. A. table are derived from Spitzglass’ formula and are, therefore, based on experimental data rather than "pure theory. Moreover, they are tabulated for actual inside diameters with their corresponding nominal diameters covering all sizes commonly used by the Gas Industry. Construction C. I. Pipe - Stand.

(Over) Authority, Distribution by Steel—Woodall & Parkinson Date Issued, January 1, 1922 - Serial No. 5 INSTRUCTIONS FOR USE OF TABLES 1, 2, 3, and 4 The accompanying tables have been computed from p ––– for low pressure, 5 Dr. Pole's formula Q=C N d l S 2 5 Pl - P 2 - and Q=C d —- for high pressure, using the | S coefficient C=1350 for diameters from five inches up- wards. Below five inches, the coefficient has been dimin- ished gradually to 1100 at one inch. Table No. 1 may, therefore, give results somewhat high for small mains if used for low pressures, but when multiplied by fac- tors for high pressures, the quantities will be on the safe side. The main object of Table No. 1 is to form a basis for the subsequent high pressure tables. Tables No. 2 and No. 3 give figures by which low pressure results may be multiplied to give delivery at high pressure for all possible pressures. The results derived from the use of the tables should be regarded as only approximate, therefore values are purposely stated in round numbers. It should be assumed that steel tubes will give results generally in excess of the tables, which are based on the coefficient for cast iron pipes. This may compensate for an occasional bend or for deposits in the main, which may diminish the capacity after years of service. Resistance set up by specials in the pipe line may be conveniently stated in terms of equivalent lengths of pipe. A round 90° elbow may be taken as equivalent to a straight pipe of a length equal to 50 times the diam- eter. A formula for this equivalent length is : r 0.83 L=12.85 (...) l Where L=equivalent length r=radius of pipe R=radius of curve l=length of curve in feet measured along the center line. Multiples given at the foot of Table No. 1 for pres- sures in inches of water up to 28 inches or one pound per square inch, are square roots of (p) in inches of water and express relationship of the flow of gas at their respective pressures with the flow given in the table at one inch pressure. Multiples are also given for various specific gravities of gas with respect to air, and results may be obtained from the table by their use. For example, to obtain values for air, multiply result obtained from the tables by 0.71. To complete the utility of Table No. 1, the delivery figures may be divided by 92 to obtain results in gal- lons of water per minute for a head of one inch. Or the same may be divided roughly by 11 (more exactly 11.44) to give cubic feet of water per hour, In all cases P, and P, represent the absolute pres- sure in pounds per square inch or gauge pressure plus 15 pounds atmospheric pressure.” LEGEND USED IN TABLE AND EQUATIONS d =diameter of main in inches. =length of main in yards. L =length of main in miles. l p =loss of pressure in inches of water. Pi—initial high pressure in pounds per square inch absolute. P.-final high pressure in pounds per square inch absolute. h =head in feet of water. S =sp. gr. Compared with air.

AUTHORITIES AND METHODS OF CALCULATION In column IX the figures given in Hempel’s “Gas Analysis,” p. 375, were selected for the fun- damental weight of oxygen, nitrogen, hydrogen, Carbonic Oxide and air. - - The formula used for the conversion to English units is – grammes per liter at 0° C. and 760 mm. X .05922 = pounds per cu. ft. at 60° F. and 30” pressure. The derivation of the factor employed is 28.316 046 * * * - .316 × .0022 X 30.00 × 492 - .05922 = 29.92 × 520 The weights of the compound gases are calculated from these data by Avogadro's law. 1 Calculated for C2 as a gas.

Suppose, for example, the outlet-water thermometer to be used was one that was immersed to the 30° F mark on the scale, and a stem-correction table were wanted for an 18° F rise in temperature, then from the above table we obtain the following stem-correction table: - w Stem Correction for outlet-water Theremometer No.— [Table applicable when inlet water is approximately at room temperature, when theremometer is immersed to the 30° F mark, and when the temperature rise is approximately 18° F.] - Inlet-water temperature - Stem correction | Inlet-water temperature Stem correction -SIF o 3F © 50 0.05 80 0.09 60 .06 90 .11 70 .08 100 .13 In the same way a table could be made out for any outlet-water thermometer by interpolation in the general table. The table so prepared would apply for the particular point to which the thermometer was immersed and for the partic- ular rise in temperature with which the observer had chosen to work. : CORRECTIONS, IN BTU, TO BE APPLIED TO OBSERVED HEATING VALUES IN CALCULATING TOTAL HEATING VALUES OF ILLUMINATING GAS (ABOUT 600 BTU) [The tabular corrections are applicable when inlet water, air, gas, and products are all at approximately the same temperature and when the Calorimeter is Operated at normal rate of gas consumption.} Temperature of room, etc. 1. . º r 20 per C © Il t 3. º r Relative humidity of air 40 per Cent 50 per Cent 60 per cent 80 per C € Ił t 90 per Cent 100 per C e Il t i I 2 | i s | i i ; : Gas tº ſº tº * A $ Testing Pacific Coast Gas Association Calorimetry Temp.
