A Brayton cycle with an air inlet temperature of 17 °C has a pressure ratio of 16. While the cycle produces 14 MW of energy, there is an input of 960 kJ/kg 1 heat into the cycle. Recognizing that specific heats change with temperature; a) Find the highest temperature (K) of the cycle. b) Find the compressor work (kJ/kg). c) Find the turbine work (kJ/kg). d) Find the mass flow rate (kg/s) of the air. e) Calculate the thermal efficiency of the cycle.
