natural state.
3.3 A container of saturated soil weighed 113.27 g before
it was placed in an oven and 100.06 g after it remained in the
oven overnight. The container alone weighs 49.31 g; the
specific gravity of the soil is 2.80. Determine the void ratio,
porosity, and water content of the original soil sample.
3.4 A saturated soil has a unit weight of 120 pcf and a
water content of 32.5%. Determine the void ratio and specific
gravity of the soil.
3.5 A sample of dry sand having a unit weight of 105 pcf
and a specific gravity of 2.70 is placed in the rain. During
the rain the volume of the sample remains constant but the
degree of saturation increases to 40%. Determine the unit
weight and water content of the soil after being in the rain.
