Determine thermal efficiency and mass flow rate of cooling

Reference no: EM13306161

A simple steam power plant operates at steady state with water circulating through the components with a mass flow rate of 100 kg/s. Stray heat transfer, kinetic energy and potential energy effects are negligible. Determine the thermal efficiency and the mass flow rate of cooling water from an adjacent river given the following information: The pressure and temperature of the steam entering the turbine are 3 MPa and 450 C respectively; the water leaving the turbine has a quality of 95% at a pressure of 60 kPa. After passing through the condenser, it is saturated liquid. The water then goes through the pump and exits at 3 MPa and 90 C where it then enters the steam generator and exits as the high pressure, high temperature steam to complete the cycle. The cooling water from the river enter the condenser at 20 deg C and is only allowed to be discharged back into the river at a temperature that is 10 deg C higher.
