WebFor example, the components of a known volume of soil are shown in Figure 1. All of the components total 100%. Since volumetric water content (VWC) equals the volume of water divided by the total soil volume, in this case, VWC will be 35%. WebWtof Solids Wtof Water TotalVolume WW V == + = + = ()1 +mW V s = (1 + m) γdry This allows us to plot the variation of dry unit weight with moisture content, giving the typical reponse shown in Figure 2 below. From this graph we can determine the optimum moisture content, mopt, for the maximum dry unit weight, (γdry)max. Moisture content Dry ...
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 WebJun 22, 2015 · (2) The optimum moisture for the total soil will be determined by the formula: Wt = (PcWc + PfWf)100 Where: Wt = Optimum moisture content for total soil, Wc = Optimum moisture content (absorption), expressed as a decimal, for material retained on No. 4 sieve (estimated between 1% and 3%),
