Acentrifugal pump is used to transport water through a l-inch schedule 40 commercial steel pipe a distance of 250 m and delivers the water to an open storage vessel 20 m above the inlet. both the inlet and outlet are at ambient pressure. the pump has a performance curve given by the expression: hsupply = ao + aj v + a2 v2 + a3 v + a4 v4, with ao = 130.0, aj +0.1371, a2 = -0.3920, a3 = 0.04047, a4 - -0.002058, with h given in feet and v given in gpm. the pipeline includes 5 threaded smooth elbows, one fully open globe valve, and one fully open gate valve. determine the flow rate. show your work.
