A steam turbine processes 2 kg/s of steam at 3 MPa, which is exhausted at 50 kPa and 100°C, see figure below. After the expansion in the high-pressure turbine, five percent of this flow is diverted for feedwater heating at 500 kPa. The isentropic efficiency of the turbines is 0.8. Determine: The power produced by this turbine in kW. The rate of entropy generated in kW/K. The rate of entropy generated in kW/K.
