How is air pressure made
Air for breathing may be stored at high pressure and gradually released when needed, as in scuba diving, or produced continuously to meet requirements, as in surface-supplied diving. Air for breathing must be free of oil and other contaminants; carbon monoxide, for example, in trace volumetric fractions that might not be dangerous at normal atmospheric pressure may have deadly effects when breathing pressurized air due to proportionally higher partial pressure. Air c… Web22 jun. 2024 · Airplanes pressurize their cabins by pumping air into them. As their jet engines suck in air, some of the excess air is diverted into the airplane’s cabin. The air is both cooled and humidified — meaning moisture is added to it — after which it’s circulated into and throughout the cabin.
