Air enters the compressor of a gas turbine at 100 kPa, 300 K with a volumetric flow rate of 5m3/sec. The air is compressed in two stages to 1200 kPa with intercooling to 300 K between stages at a pressure of 350 kPa. The turbine inlet temperature is 1400 K and the expansion occurs in two stages with reheat to 1340 K between the stages at a pressure of 350 kPa. The compressor and turbine stage efficiencies are 87% and 85% respectively. Determine (i) the thermal efficiency of the cycle, (ii) the back work ratio, (iii) the net power developed in kW. Draw the schematic diagram of the cycle and indicate the process on T-s diagram. Assume effectiveness of the regenerator as 80%. Assume CP = 1.005 kJ/kg-K for air and gas.
