In a 35,000 kW turbo-generator that receives steam at 6.9 MPa and 370°C, m1 is actually extracted at 2.1 MPa; with the remainder being reheated to 315°C; then m2 is actually
extracted at 0.724 MPa, each extraction serving an open feedwater heater. The engine exhaust to a condenser pressure of 0.005 MPa. For an ideal engine, find (a) hourly quantities of steam extracted, (b) W, (c) e.
