1. What is the Pool Volume Formula?

The pool volume formula calculates the water capacity of a circular above-ground pool in gallons. It takes into account the pool's radius and average depth to determine the total volume of water needed to fill the pool.

2. How Does the Calculator Work?

The calculator uses the pool volume formula:

Where:

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

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

3. Importance of Pool Volume Calculation

Details: Knowing your pool's volume is essential for proper chemical treatment, pump sizing, and maintenance. Accurate volume calculation ensures proper water balance and efficient operation.

4. Using the Calculator

Tips:

• For a standard 30ft pool, the radius is 15 feet
• Measure depth at both shallow and deep ends and average them
• All values must be positive numbers

5. Frequently Asked Questions (FAQ)

Q1: Why is 7.48 used in the formula?
A: 7.48 is the conversion factor from cubic feet to gallons (1 cubic foot = 7.48 gallons).

Q2: How do I measure average depth?
A: Measure depth at both ends (if applicable) and calculate the average. For uniform depth pools, use that single measurement.

Q3: What's the volume of a standard 30ft pool?
A: A 30ft diameter pool (15ft radius) with 4ft depth holds about 21,150 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: It's accurate for perfectly cylindrical pools. Irregular shapes or slopes may require more complex calculations.
