A steam power plant with a capacity of 200 MW operating on a simple nonideal Rankine cycle. Steam enters the turbine at 12.5 MPa
A steam power plant with a capacity of 200 MW operating on a simple nonideal Rankine cycle. Steam enters the turbine at 12.5 MPa and 525C and is cooled in the condenser at a pressure of 10 kPa and the water leaving the condenser is subcooled by 5.81C. The isentropic efficiency for the turbine is 85% and that of the pump is 90%. Determine: (i) the quality of the steam at the turbine exit (units: unitless), (ii) the thermal efficiency of the cycle (units: %), (iii) the enthalpy at the turbine exit (units: kJ/kg), (iv) the net work output (units: kJ/kg) and (v) the mass flow rate of the steam (kg/s).
