Question:

A sample of sand has a relative density of 40% with a specific gravity of solids of 2.65. The minimum void ratio is 0.45 and the maximum void ratio is 0.97.

(a) What is the unit weight (in units of pcf) of this sand in the saturated condition?

(b) If the sand is compacted to relative density of 65%, what will be the decrease in thickness of a 4 ft. thick layer?
