FIELD: measurement of permeability of materials under conditions of volumetric filtration. SUBSTANCE: procedure includes measurement of initial volume of material, placement of material into chamber with liquid, rise of pressure in chamber to force liquid into material, replacement of gas present in pores of material, measurement of time of replacement of gas by liquid, measurement of volume of liquid forced into material. Then permeability of material under conditions of volumetric filtration is found with due account of additional corrections related to compressibility of liquid and deformability of material, parameter of geometric dimensions and value of volume viscosity. EFFECT: increased accuracy and speed of measurement of permeability. 17 cl, 10 dwg \
