A Brayton cycle operates with an inlet temperatures of 1500 K and 320 K for the turbine andcompressor respectively. The compressor pressure ratio is 12 and air arrives at the

compressor at110 kPa. Draw the process and T-S diagrams. Calculate the efficiency of the cycle. Calculate the back work ratio. How does the cycle compare with real world Brayton cycles? Is it better or worse than most?it unreasonably good or truly awful?
