A centrifugal pump having a performance curve given by the equation h, = 170 – 122.884Q², with h, in feet when Q is in ft³/s, is to be used with a system shown in the figure below. For z2 – 71 = 40 ft, what is the expected flowrate if the total length of constant diameter pipe is 550 ft and the fluid is water? Assume that the pipe is smooth and its diameter is 4 in.
