Homework No. 1 – WeightVolume Calculations
1.
A cube of moist soil weighs 215 lb and has a volume of 2.00 ft
3
2.
A specimen of
.
Its moisture
content is 25.0% and the specific gravity of solids is 2.70.
Compute the void
ratio, porosity, degree of saturation, and the unit weight of this soil.
saturated
3.
A sand has a dry unit weight of 105 pcf and a specific gravity of solids of 2.65.
What water content will give the sand a degree of saturation of 35 percent?
soil has a water content of 145 percent and a total unit
weight of 84 pcf.
Find the void ratio and the specific gravity of solids.
4.
A particular soil has a total (moist) unit weight of 122 pcf and a dry unit weight of
101 pcf.
The specific gravity of solids is unknown; you may assume that it is
2.70.
Calculate the water content and the degree of saturation.
