The resistance of a porous medium to a fluid streaming through it is estimated by minimizing the rate of energy dissipation for a class of trial stress distributions. Rigorously valid lower bounds on the resistance are obtained in terms of certain two- and three-point averages characterizing the medium. Results are given for flow both with and without slip at the pore walls.
