5. An ideal Brayton cycle with regeneration has a pressure ratio of 9. Air enters the compressor at 275 K and exits at 555 K while it enters the turbine at 1175 K. The isentropic efficiency of the turbine and the effectiveness of the regenerator are given to be 85 percent and 73 percent, respectively. (a) Show the cycle on a T-s diagram. (b) Assuming constant specific heats (cold-air-standard-assumptions), determine the heat transferred in the regenerator and the thermal efficiency of the cycle.
