Consider a system that uses both an insulated pump and an insulated turbine, with water as the working fluid. The pump is used to increase the pressure of saturated liquid water at 50 kPa to a pressure of 5 MPa. The water is then boiled, and the turbine is used to produce power from steam expanding from a saturated vapor at 5 MPa to a pressure of 50 kPa. Consider the net power from the system to be equal to the sum of the pump and turbine powers. The mass flow rate of the water through the system is 25 kg/s. Determine the net power from the system and the entropy generation rates from the pump and turbine if (a) the pump and turbine are both isentropic, and (b) the isentropic efficiencies of the turbine and pump are both 0.80.
