A sand sample above the water table has a natural moisture content of 15% and a total unit weight of 18.84 kN/m3. Laboratory tests on the dried sample give minimum and maximum void ratios of 0.50 and 0.85, respectively. Assuming G = 2.65 and unit weight of water = 9.81 kN/m3, calculate the degree of saturation and relative density.
