PDE - Single phase porous media flow through fracture

I have built a single phase gas flow in a horizontal fractured well model using the general PDE. My model is in 2 D. I want to know how can I calculate rate (mass flux)? I found an expression in Derived Values under General Form PDE that says (dflux.P). When I have done this integration it gives me a close result to the line integration of the PDE ((density*Permeability/viscosity)P) along the outlet of the system.
So I want to know if the flux is in Mass per meter of or per m^2.
Also, I want to know how can I calculate the integration of the following expression ("density*permeability/viscosity"dP) from P equals P1 to P equals P2. I do not know how to write it in Comsol especially that the system is 2 D.
Many thanks,
