Question
Steam at 6.2 MPa and 480°C is received by a regenerative engine. Extractions for feedwater
heating occurs at 3 MPa and again at. 1.4 MPa,with the remaining steam expanding to
0.0065 MPa. For the ideal engine with a throttla flow of 54,500 kg/h, find the hourly
quantities of steam ex-tracted, the turbine work in kW, and the thermal efficiency. For an ideal cycle through the same states, calculate Q and e。
