1. What is the Circular Pool Volume Formula?

The circular pool volume formula calculates the total gallons of water needed to fill a round swimming pool. It accounts for the pool's radius, average depth, and converts cubic feet to gallons.

2. How Does the Calculator Work?

The calculator uses the circular pool volume formula:

Where:

• \( V \) — Volume in gallons
• \( R \) — 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 in cubic feet and converts it to gallons (1 cubic foot = 7.48 gallons).

3. Importance of Pool Volume Calculation

Details: Knowing your pool's volume is essential for proper chemical treatment, pump sizing, and maintenance. An accurate volume calculation ensures you add the correct amount of chemicals and operate equipment efficiently.

4. Using the Calculator

Tips:

• For a 24-foot diameter pool, enter 12 feet as the radius (half of diameter)
• Measure depth at both shallow and deep ends and average them
• All values must be positive numbers

5. Frequently Asked Questions (FAQ)

Q1: 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.

Q2: How do I measure average depth?
A: Add the shallow end depth to the deep end depth, then divide by two. For uniform depth pools, just use that measurement.

Q3: What's the volume of a standard 24' round pool?
A: A 24' round pool (12' radius) with 4' depth holds about 13,500 gallons (π × 12² × 4 × 7.48 = 13,536 gallons).

Q4: Does this work for oval pools?
A: No, this formula is for circular pools only. Oval pools require a different calculation.

Q5: How accurate is this calculation?
A: Very accurate if measurements are precise. Account for any irregular shapes or slopes in your pool.
