Air enters a gas turbine with two stages of compression and two stages of expansion at 100 kpa and 17Β°c. this system uses a regenerator as well as reheating and intercooling β the intercooler returns the air to the inlet temperature. the pressure ratio across each compressor is 4 ; 300 kj/kg of heat are added to the air in each combustion chamber; and the regenerator operates perfectly while increasing the temperature of the cold air by 20Β°c. determine the systemβs thermal efficiency. assume isentropic operations for all compressor and the turbine stages and use constant specific heats at room temperature.

Compare the maximum rate of heat transfer to the basal metabolic rate by converting a bmr of 88 kcal/hr into watts. what is the value? from this comparison you should see why the body can accommodate a modes amount of activity in hot weather but strenuous activity would increase the metabolic rate above the body's ability to remove heat [12].
