A Rankine-cycle power plant has one stage of reheat. The steam at the turbine inlet is at 500°C and 3 × 10⁶ Pa. After expansion to 0.5 × 10⁶ Pa, the steam is reheated to 500°C, and expanded in a second turbine to a condenser pressure of 0.007 × 10⁶ Pa. The steam leaves the condenser as saturated liquid. Calculate the cycle efficiency, using a pump isentropic efficiency of 0.65 and a turbine isentropic efficiency of 0.90 for both turbines.
