Steam enters the high-pressure turbine of a steam power plant that operates on the reheat Rankine cycle at 10 MPa and 600°C and leaves at 4 MPa. Steam is then reheated to 500°C before it expands to a pressure of 30 kPa. The enthalpy of steam is 3330 kJ/kg at the exit of the high-pressure turbine, and 2600 kJ/kg at the exit of the low-pressure turbine. Disregarding the pump work, the cycle efficiency is Steam enters the high-pressure turbine of a steam power plant that operates on thereheat Rankine cycle at 10 MPa and 600°C and leaves at 4 MPa.
