True : B. There are currently no items in the cart ; Close. The total unit weight of a soil (the solids-water-air system), denoted g, is the ratio of the total weight to the total volume occupied: The saturated unit weight, denoted g sat, is the total unit weight that would be obtained if the air voids were filled with an equal volume of water (S = 100% and Vw = V). Density of water= 1 000kg/m^3. The weight of the dry solid matters contained in a unit volume of soil, i.e., weight of soil particles ÷ total volume of soil, (determined after the water has been dried without bulk volume change) is termed Dry Density. Density — The mass per unit volume of a soil or one of its components. x) Saturated unit weight . Here, γ m is moist unit weight, γ w is unit weight of water, G s is specific gravity, e is void ratio and ω is the water content. We simply measure mass and volume and divide volume into mass: \[\text{Density} = \dfrac{\text{mass}} {\text{volume}}\] or \[\rho = \dfrac{\text{m}} {\text{V}}\] where ρ = density m = mass V = volume. kg / m2 [B].
