1. A 10,000 kW turbo-generator operating at rated capacity receives 52,000 kg/h of steam at 2.90 MPa and 310 degrees Celsius, exhaust is at 0.007 MPa at 1.20 MPa and 230 degrees Celsius, there are actually extracted actually extracted 20% of throttle flow of regenerative heating of feedwater. The generator efficiency is 95%. For ideal engine, find (a) the quantity of steam extracted, kg/h (b) W and (c) e. For the actual, (d) the temperature of feedwater from the open heater, (e) nk, and (f) the approximately enthalpy exhaust steam and its quality Ans. (a) 12428 kg/h; (b) 787.3 kJ/kg; (c) 35.48% ; (d) 167.5 degree Celsius; (e) 87.9%; (f) 2143.8 kJ/kg. 82.2%​
