Default modeling flow through a filter medium

Hi, I am trying to simulate flow through a filter medium which goes into an application. I donot know the pressure drop across it. I have 2 queries in this regard.

1. Can we model a part of the filter medium (say 20 rectangular slots or so), apply symmetry boundary and still get the pressure drop value ? Will it be the same as opposed to 4000 solots for example??

2. Is CFD required for this or can this be and if so can validated with hand calculations ?

Any comments will be highly appreciated. Thanks.

... may be it is 'porous media' modelling you are looking for?

I cannot use Porous media, since the pressure drop is unknown across the filter. How best do i model this otherwise ? Thanks.
