Specific gravity of soil used to get porosity

WebUsually, particle density is expressed in units of grams per cubic centimeter (g/cm 3 ). An average value for particle density is 2.66 g/cm 3. This means that a soil particle that is 1 cubic centimeter in volume weighs 2.66 g. In comparison, water has a density of 1 g/cm 3, and organic matter has a density of 0.8 g/cm 3. WebSoil’s specific surface area (s, m2/g): Depends on shape of soil particle. For example, if spherical (r = radius and ρ = density) Surface area (a) = 4π r2 Mass (m) = ρV = ρ[4πr3/3] …
