Derive an expression for the bulk density of the partially saturated soil in terms of the specific gravity of the particles Gs, the void ratio e, the degree of saturation Sr and the density of water.

Question

In a sample of clay the void ratio is 0.73 and the specific gravity of the particles is 2.7. If the voids are 92 per cent saturated, find the bulk density, the dry density and the percentage water content.

What would be the water content for complete saturation, the void ratio being the same?
