A steam power plant operates on an ideal regenerative Rankine cycle with one open feedwater heater. Steam enters the turbine at 6.0 MPa and 480 °C and exhausts to the condenser at 20 kPa. Steam is extracted from the turbine at 0.6 MPa and the water leaves the feedwater heater as a saturated liquid and is pumped into the boiler. The mass flow rate of steam through the boiler is 6 kg/s. (a)The thermal efficiency of the power plant is nearest to.(b) The rate of heat transfer to the working fluid in the boiler is nearest to. (c) The quality of steam leaving the turbine is nearest to.
