A simple Rankine cycle has a pump with an isentropic efficiency of 70%. The inlet and outlet pressures of the turbine are 6 MPa and 0.075 MPa, respectively, and steam enters the turbine at 550°C. Determine a) the isentropic efficiency of the turbine if the quality at the turbine outlet is to be ? = 1, b) the thermal efficiency of the cycle, c) the rate of heat input into the boiler if the net power output of the cycle is 10 MW.
