A commercial airliner is flying at an altitude where the temperature and pressure of the air are -50°C and 26.5 kPa. An engine-driven compressor will take this air at T= -50°C, P₁ = 26.5 kPa and compress it to P₂ = P₂ = 85.0 kPa to pressurize the cabin. The air will be very hot when it exits the compressor, so a heat exchanger will be used to cool the air to T, = 20°C before it enters the cabin. Cold air at T₁ = -50°C will be used in the heat exchanger to cool the cabin air, and this air will exit the heat exchanger at T = 20°C (this air will be used to heat the cargo bay). The mass flow rate of the air delivered to the cabin is 0.80 kg/s and the compressor efficiency is 75%. Model the air as an ideal gas having constant specific heat, using 300 K values from Cengel's tables posted on Canvas. a) Find the actual temperature of the air exiting the compressor and the power input to the compressor (answers: 67.6°C and 94.5 kW). b) Find the rate of heat transfer in the heat exchanger and…
