(a) In a sample of clay soil, the void ratio (e) is 0.73, solids specific gravity (G) 2.71 and degree of saturation (S) 92%. Calculate (i) the water content, and bulk and dry densities, and (ii) the water content if the soil were saturated. Some useful definitions and formulae: e = V₂/V₁, Sr= (w/V)100 %, w = (Mw/Ms) 100 %, p = M/V, Pa = Ms/V, eS, = Ms/V, eS, wGs, Pa = p/(1+w), and Gs = Ms/VsPw.
