Really? Permeability is the same for all the flow velocity? If it's only for low velocity, is there a way to calculate it manually?

Question (Need help!)Question about permeability calculation

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
