Dry Unit Weight from Moisture Content
Easyunit weightphase relationships
A soil has moist unit weight γ = 19 kN/m3 and gravimetric water content w = 10%. What is its approximate dry unit weight?
- A15.5 kN/m³
- B17.3 kN/m³
- C19.0 kN/m³
- D20.9 kN/m³
Show solutionHide solution
Answer: B. 17.3 kN/m³
γd = γ/(1 + w) = 19/(1 + 0.10) = 17.27 kN/m³, approximately 17.3 kN/m³. Use water content as a decimal.
