A pump operating at steady state receives 1.5 kg/s of liquidwater at 50oC, 1.5 MPa. The pressure of the water at thepump exit is 14 MPa. The magnitude of the work required by the pumpis 25.2 kW. Stray heat transfer and changes in kinetic andpotential energy are negligible.
Determine the work required by a reversible pump operating with thesame conditions, in kW, and the isentropic pump efficiency.
