Steam enters a turbine at 6000 kPa and 600°C and exits as a saturated vapor at 0.02 MPa, producing power at a rate of 2000 kW. Changes in kinetic and potential energy of the flowing fluid can be ignored. If the volumetric flow rate of steam at the turbine inlet is 8.16m³/s, determine a) the rate of heat transfer, in MW, for a control volume including the turbine and its contents, and b) the total rate of entropy production, in kW/K, due to this process (i.e., the rate of entropy production in both the turbine and the surroundings) if the surroundings are at 25°C.
