"An ideal reheat Rankine cycle operates between the pressure limits of 10 kPa and 8 MPa, with reheat occurring at 4 MPa. The temperature of steam at the inlets of both turbines is 500°C, and the enthalpy of steam is 3185 kJ/kg at the exit of the high-pressure turbine, and 2247 kJ/kg at the exit of the low-pressure turbine. Disregarding the pump work, determine the work of the turbines. The inlet enthalpies must be listed and the work of the low and of the high pressure turbines per unit mass.

Using the problem above given the high-pressure turbine work per unit mass (whp) and the low-pressure turbine work per unit mass (wlp) and the heat input of the steam generator initial pass (qsg1) and reheat (qrh) per unit mass write down the relationship to determine the thermal efficiency.
