## Determine the net power per unit mass flow rate (kJ/kg) and the cycle thermal efficiency

1. Air enters the compressor of a Brayton cycle at 20°C and 1 atm. The turbine inlet state is at 800°C and 3.4 atm. Determine the net power per unit mass flow rate (kJ/kg) and the cycle thermal efficiency

2. Solve Problem 8.76 using helium as the working fluid instead of air. Compare your results to the results of Problem 8.76.

Problem 8.76

Air enters the compressor of a Brayton cycle at 20°C and 1 atm. The turbine inlet state is at 800°C and 3.4 atm. Determine the net power per unit mass flow rate (kJ/kg) and the cycle thermal efficiency
