A sample of sand above the water table was found to have a naturalmoisture content of 10% and a unit weight of 120 lb/ft^3. Laboratory tests on a driedsample indicated values of void ratio as 0.45 and 0.90, for the densest and looseststates respectively. Compute the (a) degree of saturation, and (b) relative density.Use GS=2.65.
. The wet density of a sample of sand found at a site is 1.85 Mg/cubic meter with a water content of 12%. The specific gravity is 2.71 (Mg/cubic meter). The maximun and minimum void ratios are 0.65 and 0.38, respectivily. Calculate the relative density of the sand at the site.
