Superheated steam at 8 MPa and 480oC leaves the steam generator of a vapor power plant. Heat transfer and frictional effects in the line connecting the steam generator and the turbine reduce the pressure and temperature at the turbine inlet to 7.6 MPa and 440oC respectively. The pressure at the exit of the turbine is 10 kPa, and the turbine operates adiabatically. Liquid leaves the condenser at 8 kPa, 36oC. The pressure is increased to 8.6 MPa across the pump. The turbine and pump isentropic efficiencies are 88%. The mass flow rate of steam is 79.53 kg/s. Determine the net power output, the thermal efficiency, the rate of heat transfer from the line connecting the steam generator and the tyrbine, the mass flow rate of condenser cooling water, if the cooling water enters at 15oC and exits at 35oC, with negligible pressure change.
