In thermodynamics, the compressibility factor (Z), also known as the compression factor or the gas deviation factor, describes the deviation of a real gas from ideal gas behaviour. It is simply defined as the ratio of the molar volume of a gas to the molar volume of an ideal gas at the same temperature and … Meer weergeven The compressibility factor is defined in thermodynamics and engineering frequently as: $${\displaystyle Z={\frac {p}{\rho R_{\text{specific}}T}},}$$ where p is … Meer weergeven In order to read a compressibility chart, the reduced pressure and temperature must be known. If either the reduced pressure or temperature is unknown, the reduced specific volume must be found. Unlike the reduced pressure and temperature, the reduced … Meer weergeven The virial equation is especially useful to describe the causes of non-ideality at a molecular level (very few gases are mono-atomic) as it is derived directly from statistical mechanics: Where the … Meer weergeven The unique relationship between the compressibility factor and the reduced temperature, $${\displaystyle T_{r}}$$, and the reduced pressure, $${\displaystyle P_{r}}$$, … Meer weergeven There are three observations that can be made when looking at a generalized compressibility chart. These observations are: 1. Gases behave as an ideal gas regardless of temperature when the reduced … Meer weergeven Deviations of the compressibility factor, Z, from unity are due to attractive and repulsive intermolecular forces.
