Volume of Water given Degree of Saturation of Soil Sample Calculator

Volume of Water Formula:

\[ V_w = S \times V_v \]

Volume of Water (cu m):

1. What is Volume of Water given Degree of Saturation?

Definition: This calculator determines the volume of water in a soil sample based on its degree of saturation and void space volume.

Purpose: It helps geotechnical engineers and soil scientists quantify water content in soil samples for analysis and construction planning.

2. How Does the Calculator Work?

The calculator uses the formula:

\[ V_w = S \times V_v \]

Where:

\( V_w \) — Volume of water (cubic meters)
\( S \) — Degree of saturation (percentage converted to decimal)
\( V_v \) — Void space volume (cubic meters)

Explanation: The degree of saturation (as percentage) is converted to decimal form and multiplied by the void space volume to determine the water volume.

3. Importance of Water Volume Calculation

Details: Knowing the water volume in soil helps determine its bearing capacity, settlement characteristics, and suitability for construction.

4. Using the Calculator

Tips: Enter the degree of saturation (0-100%) and void space volume (must be > 0). The calculator automatically converts the percentage to decimal.

5. Frequently Asked Questions (FAQ)

Q1: What is degree of saturation?
A: It's the ratio of water volume to void space volume, expressed as a percentage (0% = dry, 100% = fully saturated).

Q2: How do I measure void space volume?
A: Void space volume can be determined through laboratory tests like porosity tests or calculated from known soil properties.

Q3: What's a typical degree of saturation range?
A: Natural soils typically range from 30-90% saturation, depending on climate and soil type.

Q4: Can saturation exceed 100%?
A: No, the calculator limits input to 0-100% as saturation cannot exceed 100% under normal conditions.

Q5: How accurate is this calculation?
A: Accuracy depends on precise measurement of saturation and void volume. Consider ±5% margin of error in field conditions.
