A soil has a dry unit weight of 17 kN/mÂ³ and water content of 20%, then what will be its bulk unit weight?

Civil Engineering : Soil Mechanics - Quiz(MCQ)

20.4 kN/mÂ³

19.3 kN/mÂ³

24.4 kN/mÂ³

22.6 kN/mÂ³

Correct Answer : 20.4 kN/mÂ³

Explanation : Dry unit weight γd = 17 kN/m³
Water content w = 20% = 0.2
Bulk unit weight γ = γd *(1+w)
γ = 17*(1+0.2)
γ = 20.4 kN/m³.
