Air at 2.5 bar, 400 K is extracted from a main jet enginecompressor for cabin cooling. The extracted air enters a heatexchanger where it is cooled at constant pressure to 325 Kthrough heat transfer with the ambient. It then expandsadiabatically to 1.0 bar through a turbine and is dischargedinto the cabin. The turbine has an isentropic efficiency of80%. If the mass flow rate of the air is 2.0 kg/s, determine(a) the power developed by the turbine, in kW.(b) the rate of heat transfer from the air to the ambient, in kW.
