Question

The ratio of weight of water to weight of dry soil is called .......

• A. void ratio
• B. degree of saturation
• C. water content
• D. unit weight of water

Hint:

Important Definitions:
Void Ratio (e): Ratio of volume of voids to volume of solids. 
Degree of Saturation (S):} Ratio of volume of water to volume of voids. 
Water Content (w):} Ratio of weight of water to weight of dry soil. 
Unit Weight of Water:} Typically taken as \(9.81 \, \text{kN/m}^3\) or \(1000 \, \text{kg/m}^3\).

Answer 1

The Correct Option is C

Water content, also known as moisture content, is a fundamental property in soil mechanics. It is defined as: \[ w = \frac{W_w}{W_d} \] Where: 
\(W_w\) = weight of water in the soil 
\(W_d\) = weight of dry soil This parameter is crucial in determining various engineering properties of soil, including strength, compressibility, and permeability.
