Water Content given Void Ratio in Specific Gravity for Fully Saturated Soil Calculator

Water Content Formula:

\[ \omega = \frac{e}{G_s} \]

Water Content (ω):

1. What is Water Content given Void Ratio in Specific Gravity?

Definition: This calculator determines the water content of fully saturated soil based on the void ratio and specific gravity of soil solids.

Purpose: It helps geotechnical engineers and soil scientists understand the water content relationship in saturated soils.

2. How Does the Calculator Work?

The calculator uses the formula:

\[ \omega = \frac{e}{G_s} \]

Where:

\( \omega \) — Water content (%)
\( e \) — Void ratio (dimensionless)
\( G_s \) — Specific gravity of soil solids (dimensionless)

Explanation: For a fully saturated soil, the water content can be directly calculated from the void ratio divided by the specific gravity of soil solids.

3. Importance of Water Content Calculation

Details: Water content affects soil strength, compressibility, and permeability, making it crucial for foundation design and slope stability analysis.

4. Using the Calculator

Tips: Enter the void ratio and specific gravity of soil. The result will be displayed as a percentage. Both values must be > 0.

5. Frequently Asked Questions (FAQ)

Q1: What is void ratio in soil mechanics?
A: Void ratio is the ratio of the volume of voids (spaces between particles) to the volume of solids in a soil mass.

Q2: What's a typical specific gravity for soils?
A: Most mineral soils have specific gravity between 2.60 and 2.80. Organic soils may have lower values.

Q3: Why is this only for fully saturated soils?
A: The formula assumes all voids are filled with water, which is only true for saturated conditions.

Q4: How accurate is this calculation?
A: It's theoretically exact for saturated soils, but actual field conditions may vary by ±5%.

Q5: Can I use this for partially saturated soils?
A: No, this formula only applies to fully saturated conditions. Different relationships exist for unsaturated soils.
