Mass of Saturated Sample given Saturated Density of Soil Calculator

Saturated Weight Formula:

\[ W_{sat} = \rho_{sat} \times V \]

Saturated Weight (kg):

1. What is Saturated Weight of Soil?

Definition: Saturated Weight of Soil is the weight per unit volume of soil when all the voids within the soil are completely filled with water.

Purpose: This measurement is crucial in geotechnical engineering for analyzing soil behavior under saturated conditions.

2. How Does the Calculator Work?

The calculator uses the formula:

\[ W_{sat} = \rho_{sat} \times V \]

Where:

\( W_{sat} \) — Saturated weight of soil (kg)
\( \rho_{sat} \) — Saturated density of soil (kg/m³)
\( V \) — Total volume of soil sample (m³)

Explanation: The saturated density is multiplied by the total volume to calculate the mass of the saturated soil sample.

3. Importance of Saturated Weight Calculation

Details: Knowing the saturated weight helps in determining bearing capacity, settlement analysis, and slope stability in wet conditions.

4. Using the Calculator

Tips: Enter the saturated density in kg/m³, total volume in m³, and tolerance percentage (default ±5%). All values must be > 0.

5. Frequently Asked Questions (FAQ)

Q1: What is typical saturated density for common soils?
A: Clay: 1700-2200 kg/m³, Sand: 1900-2200 kg/m³, Gravel: 2000-2300 kg/m³.

Q2: Why include a tolerance percentage?
A: The tolerance accounts for measurement uncertainties and natural variations in soil composition.

Q3: How is total volume measured?
A: Typically measured using water displacement method for irregular samples or direct measurement for regular shapes.

Q4: What affects saturated density?
A: Particle density, void ratio, and degree of saturation all influence saturated density.

Q5: How does this differ from dry density?
A: Dry density excludes water weight, while saturated density includes maximum water content in voids.
