### Thermodynamics Rankine cycle efficiency problem

An ideal reheat Rankine cycle operates between the pressure limits of 20 kPa and 8 MPa, with reheat occurring at 3 MPa. The temperature of steam at the inlets of both turbines is 500Â°C, and the enthalpy of steam is 3104 kJ/kg at the exit of the high-pressure turbine, and 2385 kJ/kg at the exit of the low-pressure turbine.
