Air enters the compressor of an ideal closed air-standard Brayton cycle at 100kPa with a volumetric flow rate of 5m^3/s. The compressor pressure ratio is 10. The maximum temperature in the cycle is 1000k and the minimum temperature in the cycle is 300k. Determine (a) the net power developed in kW (b) the back work ratio, and (c) the thermal efficiency of the cycle . You may assume air to behave like an ideal gas and use the cold air-standard assumption in your analysis. show T-s diagram.
