RESUMO
In this work we study equations that describe laminar flow through a rigid isotropic granular (non consolidated) porous medium subjected to a external force field. Firstly we present the meaning of the many phisical terms of the equation and some interpretation, also a general deduction of this equation is presented. Secondly, knowing the system porosity and using Faedo-Galerkin method we obtain results of existence of weak solutions in Sobolev spaces.
