An Air standard Brayton cycle has air enter the compressor at 270C and 100 kPa. The pressure ratio is 10, and the maximum allowable temperature in the cycle is 1350K. Determine the pressure and the temperature at each state in the cycle, and the compressor work, the turbine work, and the cycle efficiency per kg of air.
