Steam enters a turbine operating at steady state at p1 = 6 MPa, T1 = 600oC with a mass flow rate of 305 kg/min and exits as saturated vapor at p2 = 20 kPa, producing power of 4.88 MW. Kinetic and potential energy effects can be ignored. Heat transfer occurs from the turbine to its surroundings which are at T0 = 30oC. Determine the magnitude of the rate of heat transfer, in kW, and the rate of entropy production, in kW/K, within an enlarged control volume that includes the turbine and enough of its surroundings for the heat transfer to occur at T0 = 30oC.
