Question: A pump has an isentropic efficiency equal to 0 . 8 . If 3 kg / s of water enter the pump at 1 0

A pump has an isentropic efficiency equal to 0.8. If 3 kg/s of water enter the pump at 100 kPa and 20\deg C and leave at 500 kPa with no noticeable change in temperature, the actual power required by this pump is most nearly equal to:
