Consider a Rnakine cycle with one reheat cycle. Steam enters the high-high pressure turbine at 7 MPa and 600 degrees C and a rate of 20kg/s, leaves at 3 MPa. It is then reheated and enters the low-pressure turbine at 2.5MPa and 500 degrees C. The condenser pressure is 20kPa, and water leaves it as saturated liquid. The isentropic efficiencies of the turbine and pump are 0.85 and 0.8 respectively. Determine the power generated by the high pressure and the low pressure, the power required by the pump, the total heat transer rate to the steam, and the thermal efficiency of this rankine cycle.
