Consider the combined gas-steam power cycle. The topping cycle is a gas-turbine cycle that has a pressure
ratio of 8. Air enters the compressor at 300 K and the turbine at 1300 K. The isentropic efficiency of the
compressor is 80%, and that of the gas turbine is 85%. The bottoming cycle is a simple Rankine cycle
operating between the pressure limits of 7 MPa and 5 kPa. Steam is heated in a heat exchanger by the
exhaust gases to a temperature of 500°C and the isentropic efficiency of the turbine is 90 %. The exhaust
gases leave the heat exchanger at 450 K. Considering the mass flow rate steam as 1 kg/s, determine:
A) Net power, B) Total input heat, C) Total entropy generation, D) Energy efficiency, E) Exergy efficiency,
F) T-s diagram
