Critical compressibility factor
Definition
Critical compressibility factor is the compressibility factor at critical temperature. It is calculated with the following formula using the values of critical pressure, critical volume, and critical temperature. Where R is the gas constant, 8.314472J/(mol*K).
Estimation Method
- MolInstincts: The Property value is estimated by the thermodynamic relationship with other properties. The estimated value is finally determined after manual inspection.
