Answer 1

Concept:

Dry density of soil is given by: \(\gamma_d=\frac{\gamma}{1+w} \)

where \(\gamma_d\) is dry density of soil; \(\gamma\) is bulk density of soil and w is water content of same soil.

Calculation:

Given: \(\gamma = 44kN/m^3; w=10%\)

So, dry density of soil is \(\gamma_d=\frac{44}{1+0.1}=40kN/m^3\)
