A sample of sand has a relative density of 40% with a specific gravity of solids of 2.65. The minimum void ratio is 0.50 and the maximum void ratio is 0.95. What is the unit weight (in units of pcf) of this sand in the saturated condition?

A sand sample has a porosity of 30% and specific gravity of solids as 2.6. What is its degree of saturation at moisture content of 4.94%?

A sample of dry sand has a volume of 1000 ml in its natural state. Its minimum volume when compacted is 750 ml. When gently poured into a measuring cylinder, its possible maximum volume is 1320 ml. what is the relative density?

An undisturbed sample of fine sand is tested in the laboratory and found to have a dry mass of 3.23 kg, a total volume of 0.00187 m3and a specific gravity of 2.65. Other laboratory tests are performed to determine the maximum and minimum density for the sand. At the maximum density, it is determined that the void ratio is 0.38; at the minimum density, the void ratio is 0.85. Determine the relative density of the undisturbed sample.
