Consider a reheat cycle with steam leaving the boiler and entering the turbine at 4 MPa and 400 C . After expanded in the turbine to 400 KPa, the steam is reheated to 400 C and then expanded in the turbine to 6 Kpa. Assuming that both the turbine and the pump are isentropic, find the thermal efficency of the cycle. (consider water enters the pump as saturated liquid).
