If a soil has a void ratio of 0.64, specific gravity of solids as 2.65, then its saturated unit weight will be ______

Civil Engineering : Soil Mechanics - Quiz(MCQ)

24.5 kN/mÂ³

25 kN/mÂ³

19.5 kN/mÂ³

25.5 kN/mÂ³

Correct Answer : 19.5 kN/mÂ³

Explanation : Voids ratio e = 0.6
Specific gravity G = 2.65
Saturated unit weight γ_sat = (G+e) γ_w/ (1+e)
γ_sat = (2.65+0.6)*9.81/(1+0.6)
γ_sat= 19.927 N/m³.
