Pseudo Critical Temperature
For gas mixtures, the gas critical pressure and temperature are called pseudocritical pressure and temperature to be distinguished from those of pure components.
Pseudocritical properties of gas mixtures can be estimated from the given gas specific gravity if gas composition is not known.
