Question

Problem 5Water vapor at 10 MPa, 600°C enters a turbine operating at steady state with a volumetric flow rate of0.36 m/s and exits at 0.1 bar and a quality of 92%. Stray heat transfer and kinetic and potential energy effects are negligible. Determine for the turbine (a) the mass flow rate, in kg/s, (b) the power developed by the turbine, in MW, (c) the rate at which entropy is produced, in kW/K, and (d) the isentropic turbine efficiency. Show this expansion process on a T-s diagram.
