Equation of State for the Real Gas:
\rho(p, T) = \frac{1}{Z} \cdot \frac{M}{R} \cdot \frac{p}{T} |
where
| Gas density | Gas pressure | Gas molar mass | |||
| Compressibility factor | Gas temperature | Gas constant |
Despite the name it covers a lot of medium-density liquids as well.
The Compressibility factor pressure-temperature dependence is usually modelled through the reduced properties
, where:
| Reduced Temperature | Сritical temperature | ||
| Reduced Pressure | Critical pressure |
Below is the list of the most popular correlations for Compressibility factor :
