In a gas turbine plant, air enters the compressor at 1 bar and 7°C. It is compressed to 4 bar with an isentropic efficiency of 82%. The maximum temperature at the inlet to the turbine is 800°C. The isentropic efficiency of turbine is 85%. The calorific value of fuel used is 43100 kJ/kg. The heat losses are 15% of the calorific value. Calculate (a) the compressor work, (b) the heat supplied, (c) the turbine work, (d) the net work, (e) the thermal efficiency, (f) the air-fuel ratio, (g) the specific fuel consumption, and (h) the ratio of compressor to turbine work. Assume c, Cpa = 1.005 kJ/kgK, Ya=1.4, Cpg 1.147 kJ/kgK, y = 1.33. In a gas turbine plant, air enters the compressor at 1 bar and 7°C. It is compressed to 4 bar with an isentropic efficiency of 82%.
