Webporosity: [noun] the quality or state of being porous. the ratio of the volume of interstices of a material to the volume of its mass. WebThe porosity is usually an isotropic property (i.e. the same in all directions); hence, the interstitial velocity is simply related to the superficial velocity by the following expression, which comes from a consideration of fluid continuity. ε U = Uo (3.1) Clearly, the resistance to fluid flow through the porous medium is
