In thermodynamics and fluid mechanics, the compressibility (also known as the coefficient of compressibility[1] or, if the temperature is held constant, the isothermal compressibility[2]) is a measure of the instantaneous relative volume change of a fluid or solid as a response to a pressure (or mean stress) change.

Compressibility refers to the measure of how a solid or fluid changes in volume when subjected to a change in pressure. It is defined as the relative volume change of a substance in response to a pressure change.

The meaning of COMPRESSIBILITY is capability of compression : the ability of something (such as a fluid) to be reduced in volume or size under pressure. How to use compressibility in a sentence.

Compressibility (also known as the coefficient of compressibility), β, is the fractional change in the volume of a fluid per unit change in pressure in a constant temperature process. Typical units are in 2 /lbf, ft 2 /lbf, 1=atm, and 1/kPa.

Compressibility: the volumetric change in a fluid when unit volume corresponds to a unit change of pressure. From: Principles of Engineering Tribology, 2023

Jan 16, 2023 · The isothermal compressibility is defined by the fractional differential change in volume due to a change in pressure. κT ≡ − 1 V(∂V ∂p)T. The negative sign is important in order to keep the value of κT positive, since an increase in pressure will lead to a decrease in volume.

Compressibility is the measure of the change in volume a substance undergoes when a pressure is exerted on the substance. Liquids are generally considered to be incompressible. For instance, a pressure of 16,400 psig will cause a given volume of water to decrease by only 5% from its volume at atmospheric pressure.

Compressibility is the measure of how much a given volume of matter decreases when placed under pressure. If we put pressure on a solid or a liquid, there is essentially no change in volume. The atoms, ions, or molecules that make up the solid or liquid are very close together.

Compressibility is a measure of how much a substance can be reduced in volume by the application of pressure. It is a fundamental property of gases, liquids, and solids that describes their ability to be compressed or squeezed into a smaller space …

Jul 20, 2022 · When the pressure is uniform on all sides of an object in a fluid, the pressure will squeeze the object resulting in a smaller volume. When we increase the pressure by ΔP on a material of volume vo, then the volume of the material will change by ΔV <0 and consequently the density of the material will also change.
