Hi,

We can calculate the permeability by the following law,

u=q/Ac=-(k/mu)(dp/dl)

u= fluid velocity
q= flow rate
k= permeability
Ac= cross sectional area
mu= viscosity of the fluid
l= length
dp/dl= pressure gradient in the direction of the flow

May I ask, for u=0 and dp/dl=0, what the permeability value is? Is it infinitely large?

I need that value to estimate(by interpolation) the permeability at low speed.

Thank you very much!
