1. What is Circular Pool Volume?

The circular pool volume calculation determines how many gallons of water a circular pool or aquarium can hold based on its radius and average depth. This is essential for proper chemical treatment and maintenance.

2. How Does the Calculator Work?

The calculator uses the circular pool volume formula:

\[ V = \pi \times R^2 \times D \times 7.48 \]

Where:

\( V \) — Volume in gallons
\( \pi \) — Approximately 3.14159
\( R \) — Radius in feet
\( D \) — Average depth in feet
7.48 — Conversion factor (cubic feet to gallons)

Explanation: The formula calculates the cylindrical volume in cubic feet and converts it to gallons.

3. Importance of Volume Calculation

Details: Knowing your pool's volume is crucial for proper chemical dosing, pump sizing, and heating calculations.

4. Using the Calculator

Tips: Measure the radius from center to edge. For depth, average shallow and deep ends if applicable. Enter values in feet.

5. Frequently Asked Questions (FAQ)

Q1: How accurate is this calculation?
A: Very accurate for perfect cylinders. For irregular shapes, consider multiple sections.

Q2: Can I use this for oval pools?
A: No, oval pools require a different formula using length and width.

Q3: What if my pool has varying depths?
A: Use the average depth (shallow end + deep end divided by 2).

Q4: Why multiply by 7.48?
A: There are 7.48 gallons in one cubic foot of water.

Q5: Can I use meters instead of feet?
A: You would need a different conversion factor (1 cubic meter = 264.172 gallons).
