1. What is the Circle Pool Volume Formula?

The circular pool volume formula calculates the total water capacity of a cylindrical pool in gallons. It accounts for the pool's radius and average depth, converting cubic feet to gallons.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( V \) — Volume in gallons
• \( \pi \) — Mathematical constant (~3.14159)
• \( R \) — Radius of the pool in feet
• \( D \) — Average depth of the pool in feet
• 7.48 — Conversion factor (gallons per cubic foot)

Explanation: The formula calculates the cylindrical volume (πR²D) in cubic feet and then converts it to gallons by multiplying by 7.48 (since 1 cubic foot = 7.48 gallons).

3. Importance of Accurate Volume Calculation

Details: Knowing your pool's exact volume is essential for proper chemical treatment, pump sizing, heating calculations, and maintenance planning.

4. Using the Calculator

Tips: Measure the pool's radius from center to edge in feet. For depth, take multiple measurements (shallow and deep ends) and average them if your pool has a slope.

5. Frequently Asked Questions (FAQ)

Q1: What if my pool isn't perfectly circular?
A: This calculator works best for true circular pools. For oval pools, use the average of length and width as diameter.

Q2: How do I measure average depth?
A: For pools with a slope, measure the shallowest and deepest points and calculate their average.

Q3: Why multiply by 7.48?
A: There are 7.48 gallons in one cubic foot of water. This converts the volume from cubic feet to gallons.

Q4: What's a typical residential pool volume?
A: Most residential pools hold between 10,000-30,000 gallons, depending on size and depth.

Q5: Can I use this for above-ground pools?
A: Yes, as long as the pool is circular. Measure the actual water depth, not the wall height.
