In an open cycle constant pressure gas turbine air enters the compressor at 1 bar and 300 K. The pressure of air after the compression is 4 bar. The isentropic efficiencies of compressor and turbine are 78% and 85% respectively. The air-fuel ratio is 80 : 1. Calculate the power developed and thermal efficiency of the cycle if the flow rate of air is 2.5 kg/s. Takec = 1.005 kJ/kg K andy= 1.4 for air andc = 1.147 kJ/kg K andy= 1.33 for gases. R= 0.287 kJ/kg K. Calorific value of fuel = 42000 kJ/kg. [Ans. 204.03 kW/kg of air ; 15.54%)
