Excerpt from Tables for Calculating the Discharge of Water in Pipes: For Water-and Power-Supplies

These Tables are intended rather for the use of hydraulic. Engineers in designing mains for water and power-supply purposes than for asoiartaining the correct sizes of service and branch pipes; odnsequently the intermediate sizes of pipes of small diarneterihave been omitted. The loss of head in friction has been calculated from the formula given in 572 of Principles of Waterworks Engineering,' by Tudsbery and Brightmore. All results in these Tables have been ob: tained by using Professor Unwin's Short Logarithmic Tables. In working out estimates of approximate cost of water supply schemes the Author has found it more convenient and axpe ditious to use gallons par hour as the unit, although for the large pipes with high vaccines these Tables only give values to the nearest hundred gllons. If greater accuracy than this is required cubic feet per second may be taken as the unit.
