In a gas turbine installation air is supplied at 1 bar, 30°C into compressor having compression ratio of 9. The air leaving combustion chamber is heated upto 1300 K and expanded upto 1 bar. A heat exchanger (regenerator) having effectiveness of 0.75 is fitted at exit of turbine for heating the air before its inlet into combustion chamber. Assuming efficiency of the compressor and turbine as 0.85 and 0.90 determine cycle efficiency, work ratio and specific work output of plant. Take Cp = 1.0032 kJ/kg -K for air.
