Steam enters the turbine from the boiler at 7 MPa, 500 C and a mass flow rate of 30 kg/s. One-fourth of the steam is extracted from the turbine at 600-kPa pressure for process heating. The remainder of the steam continues to expand and exhausts to the condenser at 10 kPa.

Learn MoreThis is not correct. It neglects the fact that some of the steam condenses in the turbine. For the adiabatic reversible expansion occurring in the turbine, the entropy per unit mass of the mixture of saturated liquid and saturated vapor leaving the turbine at 1 Bar must equal the entropy per unit mass of the dry saturated vapor entering the turbine at 5 bars.
