Air is considered as an ideal gas. Don't use gas table for gas properties, just assume that both cv and cp are constants. For air, cv=717, cp=1003, and R=287 J/kgK
Air enters the compressor of an ideal air-standard Brayton cycle at 100 kPa, 300 K, with a mass flow rate of 5 kg/s. The compressor pressure ratio is 10. For a turbine inlet temperature of 1500 K, calculate the thermal efficiency of the cycle, the back work ratio, the net power output, and the total heat transferred in the combustion chamber.
