Unless your velocities range from 0 to 5000 m/s (unlikely), go for 1 constant value.

If your resistance is constant and your velocity fluctuates then your pressure is a direct result of this....

I understand, but when you say that your velocity goes from 0 to 2.5 [m/s]. Do you mean distributed over the face of the porous media? or is varying in time?
Either way, I still can not find a good...

Thats the whole idea of a porous media coefficient, your Pi and Pv stay constant while your dp and v change.

for dp/dl=Pi*v^2+Pv*v

--> dl, Pi and Pv remain constant

Just plot your...

Visharoon,

I dont think he needs resistance in function of velocity,

Lukas
Pi = dp/dl * 1/vē --> this is your formula, so I have no idea where you get that Pi is in function of v???
Pi is...

Your inertial resistance is in function of your velocity??? OK I have never heard of this but for everything a first time.
When i derive my inertial and viscous factor, i usually have experimental...
