In a gas turbine cycle, the condition of air at the entrance of compressor is 1 bar and 27°C. Pressure ratio is 6. Maximum temperature is 700°C. The exhaust pressure of turbine is 1 bar. Assume 100% efficiency of compressor and 95% efficiency of both turbines and combustion, fall in pressure through combustion chamber is 0.1 bar, calculate:

the air-fuel ratio.

C_p
= 1.005 kJ/kg

C_pg
= 1.147 kJ/kg

C_V
= 42,700 kJ/kg
