Darcy’s Permeability

Darcy’s Law relates the volumetric flow rate Q through a porous media in response to a pressure gradient $latex \Delta P $. … $latex Q = \frac{\kappa A}{\mu}\frac{\Delta P}{L} $ Where $latex \kappa $ is the intrinsic permeability of the

Hydraulic Permeability

The hydraulic permeability of a membrane is the inverse of the fluid resistance normalized to the membrane area. Experimentally it is found with $latex \epsilon = \frac{Q}{\Delta P \, A_m}$ Where Q is the measured flow rate, $latex \Delta P
