Porosity void ratio relationship

WebThe void ratio is defined as the ratio of the void volume to the solid volume. Formula (7) is the relationship between the When the content of fine particles is large, the added solid volume of void ratio and the primary porosity. fine particles (Vf0’) occupy a space in the void volume (ΔVφ), and the volume of pore space are Vφ+ΔVφ.

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… WebVoid ratio can be greater than unity. AND Porosity lies between 0 and 100%. False: Water content is always less than 100%. If void ratio of a soil is 0.2, then its porosity will be? n = e / (1+e) 16.7 % If the specific gravity of soil solids is 2.67, and water content is 32% for a given soil, its void ratio will be? e = w*Gs / S polymaster troughs
