Unit Weight
1. The unit weight of dry soil is greater than the unit weight of wet soil.
2. The unit weight of soil decreases due to submergence of water.
3. A soil has a bulk density of 22 kN/m3 and a dry density of 20 kN/m3. Determine the water content of the soil.
4. If the soil sample has a porosity of 30% and a specific gravity of solids, G = 2.7, then its dry unit weight will be ____ (assume unit weight of water, γw = 9.81)
