An ideal Brayton cycle uses air as a working fluid. The air enters the compressor at 101 kpa and 37 C. The pressure ratio of the compressor is 12:1, and the temperature of the air as it leaves the turbine is 497 C. The temperature and the pressure of the surroundings are 37 C and 100 kpa, respectively. Use the air-standard assumptions and determine the following quantities: (a) The work per unit mass required to operate the compressor; (b) The work per unit mass produced by the turbine; (c) The heat transfer per unit mass during the combustion process and during the exhaust process; (d) The irreversibility of the cycle on a unit-mass basis, assuming the temperature of the low- and high-temperature reservoirs ar 37 C and 1300 C, respectively; (e) The thermal efficiency of the cycle.
