In a reheat-cycle power plant, steam enters the high-pressure turbine at 5 MPa, 450°C, and expands to 0.5 MPa, after which it is reheated to 450°C. The steam is then expanded through the low-pressure turbine to 7.5 kPa. Liquid water (Vi 0.001 m/kg) leaves the condensor at 30°C, is pumped to 5 MPa, and returned to the steam generator. Each turbine is adiabatic, with an isentropic efficiency of 81.6 % and the pump efficiency is 848 %. If the total...
