Detailed explanation-1: -Effective porosity can be qualitatively defined as the ratio of the volume of interconnected pore volume available for flow to the total volume of porous material. Then, by definition, effective porosity is smaller than total porosity, which is the ratio of total pore volume to total volume of porous material.

Detailed explanation-2: -An increase in porosity results in an increase in saturation at the same capillary pressure due to an increase in pore size. At the same porosity, higher saturations are observed at the same capillary pressure with an increase in the particle radius which also increases pore size.

Detailed explanation-3: -Pore size is genetic You may have your ancestors to blame or thank for the state of your pores, because pore size is largely determined by your family tree. People who have inherited naturally oily skin are likely to have larger pores because they are more actively releasing oil through wider openings.

Detailed explanation-4: -Porosity is the percentage of void space in a rock. Porosity is the percentage of void space in a rock. It is defined as the ratio of the volume of the voids or pore space divided by the total volume.

Detailed explanation-5: -X-ray refraction reveals the inner surface concentrations of porous materials within the range of m-to nm-dimensions. This technique is compared to mercury pressure porosimetry which is a standard method for pore size determination in porous solids.
