Calculating pressure loss through porous plastics
Calculating pressure loss through porous plastics
(OP)
Hello everyone,
I am looking for a way to calculate the pressure loss through porous plastics, without data from a manufacturer.
Is there any global theory about this? Or is one always refered to the manufacturers data ?
Off course some information is required, like outer velocity/pressure and porosity of the material, but this is available.
Thanks in advance

But the problem is that you need the coefficients C1 and C2, and I don't have those.
I could retrieve them from experiments, but I'd like to skip those. Is there a database for these kind of coefficients ?
I want to find the relation between pressure loss and velocity, and not only calculate the pressure.

For diffusion and mass transport of liquids, vapours and gases through porous plastics, the following reference may be useful: http://www.diffusion-polymers.com/forum.htm
