Determine the void ratio, e and the porosity,

For a soil sample in a natural condition, void ratio (e) is 0.67, degree of saturation (S) is 75%, Gs=2.7, calculate: a) dry unit weight b) total unit weight c) saturated unit weight d) initial water content and water content at saturation. f) if the void ratio was reduced to 0.5, what will be the final specific gravity.

The field unit weight of the soil is 1960 kg/m³ and the unit weight of the soil particle is 2700 kg/m3 . If the emax=0.69 and emin=0.44, a)Compute the void ration of the soil sample. bCompute the dry unit weight in KN/ m3 if water content is 11%. cCompute the relative density of the soil sample. A soil having a sp. Gr. of 2.74 has a moist unit weight of 20.6 KN/m3 and a moisture content of 16.6%. a Compute the void ratio. bCompute the degree of saturation. cCompute the effective unit weight. dCompute the weight of water in KN to be added per cu. m. of soil for 100% degree of saturation.
