Challenge Problems
Push your limits with challenges.
Question 1
Given a soil sample with a specific gravity of 2.68 and a void ratio of 0.65. Calculate the dry unit weight when the bulk density is known to be 18 kN/m³.
💡 Hint: Make sure to use the relationship of specific gravity and void ratio properly.
Question 2
A soil sample has a moisture content of 15%. If the moist unit weight is found to be 21 kN/m³, what is its dry unit weight?
💡 Hint: Convert the percentage to decimal before applying.
