n: the algebraic sum of the actual compressibility of a liquid and the volume change per unit volume of the confining container caused by a unit change in pressure at constant temperature.

n: The character of compact degree in the condition that the cake is pressed.

n: the change in volume per unit of volume of a liquid caused by a unit change in pressure at constant temperature. compressibility factor n: the ratio of the actual volume of gas at a given temperature and pressure to the volume of gas when calculated by the idea] gas law.

the volume change of a material when pressure is applied.

a difference in porosities caused by the compressibility of gas in porosities estimated by the formation density log and the neutron density log.

n: a term some- times used to mean compressibility factor, but more often to mean the compressibility factor that is appropriate for high-pressure calculations. See compressibility facto7:

n: a deviation of natural gas from Boyles and Charless laws for ideal gas. Natural gas is not an ideal gas in that it is a mixture of several gases. As the pressure increases, the volume of space that a given weight of natural gas would occupy becomes increasingly smaller than the volume calculated by application of Boyles and Charless laws.

the compressibility correction index used in the ideal gas law. Z = Vactual / V ideal
