Question

Steam enters a turbine operating at steady state at inlet pressure of 8 MPa, and inlet temperature of600°C with a mass flow rate of 130 kg/min and exits as saturated

vapor at 20 KPa, producing power at a rate of 3 MW. Kinetics and potential energy effects can be ignored. (15 points) Determine (a) the rate of heat transfer, in KW, for a control volume including the turbine and its contents,and (b) the rate of entropy production, in KW/K, for an enlarged control volume that includes the turbine and its surroundings that transfer occurs at the ambient temperature, 27°C.
