3. Water is the working fluid in a Rankine cycle. Superheated vapor enters the turbine at 10 MPa, 480 C, and the condenser pressure is 6 kPa. The turbine and pump have isentropic efficiencies of 80% and 70% respectively. Determine for the cycle (a) the heat transfer to the working fluid passing through the steam generator in kJ/kg, (b) the thermal efficiency, and (c) The heat transfer from the working fluid passing through the condenser to the cooling water in kJ/kg
