The total unit weigh of soil is 22kN/m^3. The specific gravity of soil particles is 2.67 and the water content of the soil is 10% The dry unit weight would be:

To find the dry unit weight of the soil, we can use the formula:<br /><br />Dry unit weight = (Total unit weight) / (1 + (Specific gravity) * (Water content))<br /><br />Given:<br />Total unit weight = 22 kN/m^3<br />Specific gravity = 2.67<br />Water content = 10% = 0.1<br /><br />Substituting the values into the formula:<br /><br />Dry unit weight = 22 / (1 + 2.67 * 0.1)<br />Dry unit weight = 22 / (1 + 0.267)<br />Dry unit weight = 22 / 1.267<br />Dry unit weight ≈ 17.41 kN/m^3<br /><br />Therefore, the dry unit weight of the soil is approximately 17.41 kN/m^3.
