Abasic open gas turbine cycle uses a pressure ratio of 8. the isentropic efficiency of both the turbine and compressor is 90%. the low pressure in the cycle is 100 kpa. the temperature limits in the cycle are 20°c and 1250°c. take k = 1.4, cp = 1.005 kj/kg k and the mass flow as 25 kg/s. (a) calculate the cycle efficiency and the nett power output. (b) if the fuel calorific value is 41mj/kg estimate the air fuel ratio.
