Porosity void ratio relationship

Used in geology, hydrogeology, soil science, and building science, the porosity of a porous medium (such as rock or sediment) describes the fraction of void space in the material, where the void may contain, for example, air or water. It is defined by the ratio: where VV is the volume of void-space (such as fluids) and VT is the total or bul… WebThe relation between porosity and void ratio. we know formula of void ratio (e) = Vv / Vs. in which Vv = Volume of Voids and Vs = Volume of Solids. Porosity formula (n) = Vv / V. Vv = …
