Based on the globular model with the use of the values of porosity and particle size, a method is presented for calculating the structure parameters of porous monofractional powder composite materials for filters. A formula for determining the average (hydraulic) radius of the capillaries of permeable materials has been obtained, which is more accurate than the Kozeny formula. The results of calculating the average radius of capillaries and of the permeability of porous powder materials by the proposed dependences are presented, which are in better agreement with experimental data than calculations by the Kozeny formula.
