Problem 9: Water vapor at 5 bar, 320°C enters a turbine operating at steady state with a 6.92 volumetric flow rate of o.65 m2/s and expands adiabatically to an exit state of 1 bar, 160°C. Kinetic and potential energy effects are negligible. Determine for the turbine (a) the power developed, in kW, (b) the rate of entropy production, in kW/K, and (c) the isentropic turbine efficiency.

Problem 9:
6.92
Water vapor at 5 bar, 320°C enters a turbine operating at steady state with a
volumetric flow rate of o.65 m/s and expands adiabatically to an exit state of 1 bar, 160°C.
Kinetic and potential energy effects are negligible. Determine for the turbine (a) the power
developed, in kW, (b) the rate of entropy production, in kW/K, and (c) the isentropic turbine
efficiency.
