# The moisture content of a soil sample is 22% and the dry unit weight is 15.65 kN/m3. If Gs = 2.67, what is the degree of saturation?

To determine

Calculate the degree of saturation.

Explanation

Given information:

The specific gravity of the soil solids (Gs) is 2.67.

The moisture content (w) is 22%.

The dry unit weight of soil (γd) is 15.65kN/m3.

Calculation:

Consider the unit weight of water (γw) is 9.81kN/m3.

Calculate the void ratio (e) using the relation.

e=Gsγwγd1

Substitute 2.67 for Gs, 15.65kN/m3 for γd, and 9.81kN/m3 for γw
