Problem 3The pipes shown in the system are all concrete. With a flow of 25 ft³/s (or cfs) of water, find the head loss(hL, AB) and the division of flow in the pipes (Q1, Q2, and Q3) from A to B. Assume: 1) f = 0.030 for all pipes;2) all the minor head losses in the system are negligible. Assume α = 1.0 throughout.AL= 3000 ftD = 14 in.L = 2000 ftD = 24 in.L = 2000 ftL= 3000 ftD = 30 in.D = 12 in.BL= 3000 ftD= 16 in.
