doubt in applying boundary condition

problem: Fluid is flowing through a multilayer porous pipe.
I know the boundary conditions for inlet which is pressure and outlet which is mass flow rate in the fluid domain
my question is:
How to define inlet and out let in the porous domain.
I assume in the porous domain as
inlet: Cartesian velocity components equal to 0
outlet : pressure equal to 0
Is my boundary condition correct?

If that matches the experiment you are trying to model then probably, yes.
But it does seem weird to have a mass flow outlet on the main flow, but zero pressure at the porous outlet. Why is it different? If the flow is not significant in the porous material just put a wall there.
