Consider a reheat Rankine cycle with a net power output of 100 MW. Steam enters the high pressure turbine at 10 MPa and 500°C and the low pressure turbine at 1 MPa and 500°C. The steam leaves the condenser at 10 kPa. The isentropic efficiencies of turbine and pump are 80% and 95%, respectively. Now assume that both compression and expansion processes in the pump and turbine are isentropic. Calculate the thermal efficiency of the ideal cycle.
