WebThe following formulas are taken from unit weights of soil: ρ = (G + Se)ρw 1 + e ρ = (G + Gw)ρw 1 + e ρd = Gρw 1 + e ρsat = (G + e)ρw 1 + e ρ ′ = (G − 1)ρw 1 + e Where m = mass of soil V = volume of soil W = weight of soil ρ = density of soil ρd = dry density of soil ρsat = saturated density of soil ρ ' = buoyant density of soil WebIf specific gravity of soil solids is 2.68, and the water content of soil is 10%, its zero-airvoid unit weight will be Yzav = Ywater / w + (1 / Gs) Ywater = 9.81 kN/m^3 w = .10 Gs = 2.68 …
