1. What is Pool Capacity Calculation?

The pool capacity calculation determines the volume of water a rectangular pool can hold. It's essential for proper chemical treatment, pump sizing, and maintenance planning. The formula calculates volume in gallons based on the pool's dimensions.

2. How Does the Calculator Work?

The calculator uses the rectangular pool volume formula:

Where:

• \( V \) — Volume in gallons
• \( L \) — Length in feet
• \( W \) — Width in feet
• \( D \) — Average depth in feet
• 7.48 — Conversion factor (cubic feet to gallons)

Explanation: The formula multiplies the pool's dimensions to get cubic feet, then converts to gallons using the conversion factor 7.48 gallons per cubic foot.

3. Importance of Pool Volume Calculation

Details: Knowing your pool's volume is crucial for proper chemical dosing, selecting the right pump and filter size, and maintaining water balance.

4. Using the Calculator

Tips: Measure your pool's length and width at their longest points. For depth, average the shallow and deep end measurements if your pool has a slope.

5. Frequently Asked Questions (FAQ)

Q1: How do I measure average depth for a sloping pool?
A: Add the shallow end depth and deep end depth, then divide by 2. For example: (3ft + 8ft)/2 = 5.5ft average depth.

Q2: What if my pool isn't rectangular?
A: Different formulas exist for circular, oval, or kidney-shaped pools. This calculator is for rectangular pools only.

Q3: Why is the conversion factor 7.48?
A: There are 7.48052 gallons in one cubic foot of water. We use 7.48 for simplicity in calculations.

Q4: How accurate does this need to be?
A: For chemical treatment, ±10% accuracy is usually sufficient. For precise measurements, consider professional measurement.

Q5: Does this work for above-ground pools?
A: Yes, as long as the pool is rectangular. Measure the inside dimensions of the pool liner for best accuracy.
