Question
The performance characteristics of a certain centrifugal pump are determined from an
experimental setup shown in the figure. When the flow rate 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 it is 55 mm.
If Z2-Z1= 0.5 m, what is the actual
head rise across the pump? Explain
how you would estimate the pump
motor power requirement.
