Steam power plant operating under a steady-flow process generates an electric power of 210 MW. Diagram of its components in the process are shown in the figure below. Saturated liquid water is pumped to raise its pressure from 10 kPa to 10 MPa while work of 15 kJ/kg is given to the pump. Heat loss from the pump is 5 kJ/kg. Steam that exits the boiler at 500°C enters the isentropic turbine. Then steam that exits the turbine becomes a saturated mixture. The turbine is well-insulated. Changes in kinetic and potential energies are negligible for all the devices.
