(c) Fig. 2 shows the schematic diagram of an industrial gas turbine. Air is compressed from 1 bar at 15oC to 14.2 bar before entering the combustor where a mixture of air and fuel with lower calorific value of 48 MJ/kg burns before entering the gas turbine at 1100oC at a pressure of 13.4 bar. The turbine outlet pressure is 1.03 bar. If the air feed rate is 19.4 kg/s and the polytropic efficiencies of both the turbine and compressor is 0.9. For the purpose of cooling, 7% of the air is bled from the compressor of which does not enter the combustor nor the turbine. The
