What is the formula for calculating dry unit weight?
Show hintHide hint
Refer back to the lesson notes.
Question 2.
If the moisture content is 10%, what is its decimal form?
Show hintHide hint
Remember to divide by 100.
3Question 3.
What is the relationship between moisture content and dry unit weight?
- A decreases with higher moisture content
- B increases with higher moisture content
- C remains unchanged
Show hintHide hint
Think about how water impacts soil structure.
4Question 4.
True or False: The dry unit weight can be higher than the saturated unit weight.
- True
- False
Show hintHide hint
Consider what saturation means.
Question 5.
A soil sample has a void ratio of 0.4 and receives water to reach saturation. If the specific gravity is 2.7 and the initial dry density is 1600 kg/m³, what is the final saturated unit weight?
