WebOil compressibility (also called isothermal oil compressibility) is defined as the change in fluid volume with respect to the change in pressure at isothermal conditions. Oil compressibility is expressed in psi−1. Another unit (microsip) is also used. A microsip is equal to 1×10 −6 psi −1.

WebThe gas formation volume factor indicates how much the gas volume would change as a response to the change in pressure. As pressure decreases, the gas sharply expands due to its high compressibility. As a result, the gas formation volume factor increases as well. Actually, almost all the black oil properties respond differently to the decrease ... Compressibility is an important factor in aerodynamics. At low speeds, the compressibility of air is not significant in relation to aircraft design, but as the airflow nears and exceeds the speed of sound, a host of new aerodynamic effects become important in the design of aircraft. These effects, often several of them at a time, made it very difficult for World War II era aircraft to reach speeds much beyond 800 km/h (500 mph).
