compressibility

…this is described by the compressibility of the fluid—either the isothermal compressibility, β_T, or the adiabatic compressibility, β_S, according to circumstance. When an element of fluid is compressed, the work done on it tends to heat it up. If the heat has time to drain away to the surroundings and…

239 calorie), and a low compressibility (0.5–1 × 10^-4 per bar). The compressibility falls to values characteristic of a solid (0.1 × 10^-4 per bar or less) as the pressure increases. A simple and widely used equation describes the change of specific volume with pressure. If V(p) is the volume…

Increasing density values demonstrate the compressibility of seawater under the tremendous pressures present in the deep ocean. If seawater were incompressible, each cubic centimetre of water in the water column would expand, and density values at all depths would be equal. If the average pressure occurring at a depth of…

…shear, or slide along planes; compressibility (the degree to which soil may be made denser by various means including tamping and vibration, and thus able to support greater loads); elasticity (the ability of soil to reexpand after being compressed); permeability (the degree to which a soil will conduct a flow…

…empirical formula for the mean compressibility (compression ratio divided by pressure) of seawater as a function of pressure and temperature. This formula is still in use today to determine density of deep seawater which is compressed by hydrostatic pressure.
