2. In a Brayton cycle air enters the compressor at 101.32 kPa, 32°C and leaves at a pressure of 808 kPa. The air is heated to 717°C in the combustor. For a net output of 2125 kW, compute (a) the rate of flow of air per second, (b) the thermal efficiency, and (c) the mean effective pressure. Ans. (a) 10.78 kg/s, (b) 44.75%, (c) 145.65 kPa
