Water vapor enters an isentropic turbine at a flow rate of 1 kg/s, a temperature of 500 °C and a pressure of 3000 kPa. Isentropic turbine has two outputs. While 20% of the inlet flow leaves the turbine at a temperature of 350°C and a pressure of 1000 kPa from one of the outlets, the remainder is separated from the other outlet at 200°C and at 200 kPa pressure. Assuming the ambient temperature is 25 °C. a) Find the isentropic efficiency of the turbine. b) Find the second law efficiency of the turbine.

Question

 Water vapor enters an isentropic turbine at a flow rate of 1 kg/s, a temperature of 500 °C and a pressure of 3000 kPa. Isentropic turbine has two outputs. While 20% of the inlet flow leaves the turbine at a temperature of 350°C and a pressure of 1000 kPa from one of the outlets, the remainder is separated from the other outlet at 200°C and at 200 kPa pressure. Assuming the ambient temperature is 25 °C.

a) Find the isentropic efficiency of the turbine.

b) Find the second law efficiency of the turbine.
