A flowrate enters a junction and is split into two pipes (Pipe P-1 and Pipe P-2) then join back together downstream. The diameters of both pipes are 12 inches and have C values of 145. The length of P-1 is 1650 feet, while the length of P-2 is 2200 feet. If the flowrate of P-1 is fixed at 940 GPM, what is the flowrate in P-2?
P1 and P2 are parallel pipes and hence their headloss are equal.
Using Hazen Williams equation, the headloss is equated and flow is found.
Flow for pipe 2= 804.625 GPM
