In a gas turbine plant, air is compressed from 1.01 bar and 15 ?C through a pressure ratio of 4. It is then heated to 650 ?C in a combustion chamber, and expanded back to atmospheric pressure. Calculate the cycle efficiency and work ratio if a perfect heat exchanger is employed. The isentropic efficiencies of the turbine and compressor are 0.85 and 0.80, respectively. ANSWER (0.319, 0.319)
