A two-stage compressor has water-jacketed cylinders and a water cooled inter cooler. The compressor takes in 500 cfm of "free" air at 14.7 psia and 80°F and discharges it into a receiver in which the pressure remains constant. Cooling water flows through jackets and the intercooler at the rate of 4 gpm, the water entering at 80ºF and leaving at 120°F. Assuming that the heat loss from the compressor to its surroundings is negligible, calculate the horsepower supplied to the compressor if the enthalpy of the air increases by 41 BTU/b.

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%.
