A Brayton cycle with regeneration using air as the working fluid has a pressure ratio of 7. The minimum and maximum temperatures in the cycle are 310 and 1150K. The isentropic efficiency is 75% for the compressor and 82% for the turbine, and the effectiveness for the regenerator is 65. Determine (a) the air temperature at the turbine exit, (b) the net work output, and (c) the thermal efficiency of the cycle. Also, determine (d) the total exergy destruction associated with the Brayton cycle, assuming a source temperature of 1800 K and a sink temperature of 310 K. Also, determine the exergy of the exhaust gases at the exit of the regenerator.
