Challenge Problems
Push your limits with advanced challenges
Calculate the necessary water to add to a soil sample with dry unit weight 16 kN/m³, moisture content 10%, and saturated unit weight 20 kN/m³.
💡 Hint: Don’t forget the formula connecting these weights.
Given a soil with a porosity of 0.4 and bulk density of 1600 kg/m³, derive its specific gravity and void ratio.
💡 Hint: Begin with understanding the relation of porosity to void ratio.
