One of the Absolute permeability models based on simulating the flow through the multi-pipe conduits or multi-grain pack:

| k = 1014.24 \cdot {\rm FZI}^2 \cdot \frac{(\phi_f -\phi_{f0})^3}{( 1 - \phi_f+\phi_{f0})^2} |

CK | {\rm FZI} = \frac{1}{\sqrt{F_S} \, S_{gV} \, \tau } |
|
where
The alternative form is derived from the correlation which is valid in some practical cases:

\frac{1}{\sqrt{F_S} \, S_{gV}} \approx 0.0037 \cdot d |
where
so that Absolute permeability is going to be:
