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… WebFlight Begins with Air in Motion. As an airplane moves through the air, its wings cause changes in the speed and pressure of the air moving past them. These changes result in the upward force called lift. To understand lift, you first have to understand how air (a gas) behaves under certain conditions.
