A centrifugal water pump operates at 1750 rpm. The rotor geometry is shown in the sketch below. The inlet blade angle is 30 degrees and the exit blade angle is 90 degrees and the blade can be assumed to occupy negligible volume. Water enters with no pre-whirl and the overall efficiency of the pump at the design point is 75%. At the design point of the pump: Determine the design point flow rate for the pump in gpm, determine the isentropic pressure rise across the rotor and determine the shaft work required
