5.2 kg/s of steam enters an adiabatic turbine at 6 MPa and 550 °C and leaves at 1.2 MPa. If the isentropic efficiency of the turbine is 0.782, calculate (a) the entropy change of the fluid during the process (kJ/K.s) (b) the power produced by the turbine (kW), and (c) the temperature at the exit. 5.2 kg/s of steam enters an adiabatic turbine at 6 MPa and 550 °C and leaves at 1.2 MPa.
