An air-standard Brayton cycle with air entering the compressor at 100 kPa and 288 K and it leaves the compressor at 1000 kPa. The maximum temperature of the cycle is 1373 K. The compressor in the cycle is rated with an isentropic efficiency of 0.8, the turbine with an isentropic efficiency of 0.85. There is a pressure drop of 15 kPa between the compressor and the turbine. a) First, let us consider an ideal Brayton with the same operating condition, i.e. a cycle with the same compressor inlet and outlet condition, as well as the maximum cycle temperature. compressor work, turbine work and cycle efficiency. Find the (8 points) (8 points) b) Find the compressor work, turbine work and cycle efficiency for the actual cycle. c) Sketch both cycles on the same T-s diagram for comparison.
