In an ideal Rankine cycle, steam enters the turbine at 10 MPa and 500 °C (ℎ = 3375.1 kJ/kg, 𝑠 = 6.5995 kJ/kg.K). It is cooled in the condenser at a pressure of 10 kPa. At 10 kPa, ℎ𝑓 = 191.81 kJ/kg, 𝑠𝑓 = 0.6492 kJ/kg.K, ℎ𝑔 = 2583.9 kJ/kg and 𝑠𝑔 = 8.1488 kJ/kg.K. The heat rejected in the condenser (in kJ/kg) is
