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 in water.
3. Unit weight of soil is defined as the ratio of:
4. 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.
5. Bulk unit weight of a soil is the unit weight when the soil is in its:
6. Which of the following correctly relates dry unit weight (γ_d), bulk unit weight (γ), and water content (w)?
7. 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 γ_w = 9.81 kN/m³).
8. For a fully saturated soil, the relationship between void ratio (e), water content (w), and specific gravity (G) is:
9. Calculate the submerged unit weight of a soil with G = 2.65 and e = 0.65 (γ_w = 10.0 kN/m³).
