Consider a reheat Rankine cycle in which the steam enters the high-pressure turbine at 7 MPa and 500°C. After the expansion process in the high-pressure turbine to 400 kPa, the steam is reheated to 500°C in the boiler and then expanded in the low-pressure turbine to 7.5 kPa. Assume that saturated liquid enters the pump, and pumping and expansion processes are isentropic. Calculate the thermal efficiency of the cycle, in %.
