Question 1
What is the formula for dry unit weight?
- γ_d = γ/(1 + w)
- γ_d = γ * (1 + w)
- γ_d = γ + w
💡 Hint: Remember the relationship taught in class.
Question 2
True or False: Saturation occurs when air fills the voids in soil.
- True
- False
💡 Hint: Think about how water affects the voids.

Challenge Problems
Push your limits with challenges.
Question 1
Given a moist unit weight of 22 kN/m³ and moisture content of 20%, calculate the dry unit weight and the amount of water needed to saturate it assuming the saturated unit weight is 25 kN/m³.
💡 Hint: Start by calculating dry unit weight and then the water required.
Question 2
A soil's void ratio is 0.5, and specific gravity is 2.7. Calculate the dry unit weight and then the moist unit weight given a moisture content of 15%.
💡 Hint: Remember the formulas and plug in values step-by-step.
