# Determine The Water Content of The Soil Sample

Rate this post

## A saturated soil sample has a dry unit weight of 18000 N/m3 and specific gravity of 2.65 if the unit weight of water is 9810 N/m3, determine the water content of the soil sample?

Explain:- Correct answer for the question A saturated soil sample has a dry unit weight of 18000 N/m3 and specific gravity 2.65 if the unit weight of water is 9810 N/m3, determine the water content of the soil sample is [B] 0.17

### Detailed Explanation for Solution

Dry unit weight (É£d) = 18000 N/m3 = 18 kN/m3

Specific gravity (Gs) = 2.65
Unit weight of water (É£w) = 9810 N/m3 = 9.81 kN/m3

#### For water Content

É£d = GÉ£w/1+wG

18 = (2.65 Ã— 9.81) / (1 + 2.65 Ã— w)
18 + 47.7w = 25.99
47.7w = 7.99
w = 0.1675
w â‰… 0.17
