The performance characteristics of a certain centrifugal pump are determined from an experimental setup. When the flowrate of a liquid (SG=0.9) through the pump is 120 gpm, the pressure gage at 1 indicates a vacuum of 95 mm of mercury and the pressure gage at 2 indicates a pressure of 80 kpa. The diameter of the pipe at the inlet is 110 mm and at the exit is 55mm. If z1-z2=0.5m, what is the actual head rise across the pump? Explain how you would estimate the pump motor power requirement.
