1. In a reheat cycle, steam at 15 Maa, 540°C, enters the turbine and expands to 1.95 MPaa. At this point the steam is withdrawn and passed through a reheater. It re-enters the engine at 540°C. Expansion now occurs to the condenser pressure of 0.0043 MPaa. a) For ideal cycle and engine, determine the thermal efficiencies, b) A 60,000-KW turbine operates between the same state points except that the steam enters the reheater at 1.95 MPaa and 260°C, departs at 1.80 MPaa and 540°C. The steam flow rate is 147,000 kg/hr; generator efficiency is 96%, find the combined thermal efficiency, the combined steam rate, and the combined engine efficiency.
