Volume of Voids given Degree of Saturation of Soil Sample Calculator

Void Space Volume Formula:

\[ V_v = \frac{V_w}{S} \]

%

1. What is Void Space Volume Calculator?

Definition: This calculator estimates the void space volume in soil based on the volume of water and degree of saturation.

Purpose: It helps geotechnical engineers and soil scientists determine the void space in soil samples for analysis and construction planning.

2. How Does the Calculator Work?

The calculator uses the formula:

\[ V_v = \frac{V_w}{S} \]

Where:

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

Explanation: The water volume is divided by the degree of saturation (as a decimal) to determine the total void space volume.

3. Importance of Void Space Calculation

Details: Proper void space estimation is crucial for understanding soil permeability, water retention, and stability for construction projects.

4. Using the Calculator

Tips: Enter the volume of water in cubic meters and degree of saturation as a percentage (0-100%). All values must be > 0.

5. Frequently Asked Questions (FAQ)

Q1: What is degree of saturation?
A: Degree of saturation is the ratio of water volume to void volume, expressed as a percentage (0-100%).

Q2: What's a typical degree of saturation for soil?
A: It varies widely - from 0% for dry soil to 100% for fully saturated soil. Most natural soils range between 20-80%.

Q3: How do I measure water volume in soil?
A: Water volume can be determined by drying a known volume of soil and measuring the weight difference.

Q4: What affects void space in soil?
A: Soil texture, structure, compaction, and organic matter content all influence void space.

Q5: Why is void space important in construction?
A: Void space affects drainage, bearing capacity, and potential for settlement in foundations.
