A generalization of the Brinkman equation to the case 
of linear filtration has been proposed based on an analysis of the 
existing models of filtration of a liquid (gas) in a stationary granular 
bed. It has been shown that, with allowance for the local-porosity 
distribution over the cross section of the apparatus, this equation 
makes it possible to describe velocity distributions observed experimentally 
in the wall zone.
