Compressibility of the fluid with density
\rho_f and molar volume
V_{mf} is a function of temperature and pressure:
| (1) | c_f = \frac{1}{\rho_f} \frac{\partial \rho_f}{\partial p} = -\frac{1}{V_{mf}} \frac{\partial V_{mf}}{\partial p} |
The multi-phase compressibility is a linear sum of compressibilities of its phases.
Mathematical model of Fluid Compressibility is reviewed in Fluid Compressibility @model.
