1. What is Total Volume Given Specific Retention?

Total Volume given Specific Retention is defined as the total capacity. It is calculated based on the volume of water retained and the specific retention percentage, which tells how much water remains in the rock after it is drained by gravity.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( V \) — Total Volume (m³)
• \( Wr \) — Volume of water retained (m³)
• \( \%Sr \) — Specific Retention Percentage (%)

Explanation: The formula calculates the total volume by dividing the volume of water retained by the specific retention percentage and then multiplying by 100.

3. Importance of Total Volume Calculation

Details: Accurate Total Volume estimation is crucial for understanding the capacity and water retention properties of materials, especially in geology and civil engineering applications.

4. Using the Calculator

Tips: Enter volume of water retained in m³ and specific retention percentage in %. All values must be valid (greater than 0).

5. Frequently Asked Questions (FAQ)

Q1: What is Specific Retention Percentage?
A: Specific Retention Percentage (in %) tells how much water remains in the rock after it is drained by gravity.

Q2: Why multiply by 100 in the formula?
A: The multiplication by 100 converts the fraction into a percentage-based total volume calculation.

Q3: What are typical values for Specific Retention?
A: Specific Retention values vary depending on the material, but generally range from a few percent to over 30% for different rock and soil types.

Q4: When is this calculation most useful?
A: This calculation is particularly useful in hydrogeology for determining aquifer properties and in civil engineering for soil moisture content analysis.

Q5: Are there limitations to this formula?
A: This formula assumes homogeneous material properties and may need adjustment for complex or layered materials with varying retention characteristics.
