B1 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 isextracted from the turbine at 0.6 MPa and the water leaves the feedwater heater as a saturated liquidand is pumped into the boiler. The mass flow rate of steam through the boiler is 6 kg/s. The quality ofsteam leaving the turbine is nearest to:O a. 0.871O b. 0.822O c. 0.894O d. 0.846An ideal reheat Rankine cycle uses water as the working fluid. Steam enters the high-pressure turbineat 10 MPa and 500 °C and expands to 2.5 MPa. It is then reheated to 500 °C and expands again in thelow-pressure turbine to the condenser pressure of 10 kPa. The heat removed from the working fluid inthe condenser is nearest to:O a. 1792 kJ/kgO b. 1922 kJ/kgO c. 2129 kJ/kgO d. 2319 kJ/kg
