Hazen and williams equation
WebAlso, Darcy-Weisbach’s and Hazen William’s head loss equations are applied in the two methods. A simple distribution network shown in Figure 1 below was analysed. It consists of a three-looped pipe network with a source reservoir. Fig-1: The Sample Network with Initial the pipe flows. The following is the Hazen-Williams equation [9, 10].
