1. What is Pool Volume Calculation?

The pool volume calculation determines the total water capacity of a swimming pool in litres. This is essential for proper chemical treatment, filtration system sizing, and maintenance planning.

2. How Does the Calculator Work?

The calculator uses the rectangular pool volume formula:

Where:

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

Explanation: The formula calculates the cubic volume of the pool and converts it from cubic feet to litres (1 cubic foot = 28.32 litres).

3. Importance of Pool Volume Calculation

Details: Knowing your pool's volume is crucial for proper chemical dosing, pump and filter selection, heating requirements, and water replacement calculations.

4. Using the Calculator

Tips: Measure your pool's length, width, and average depth in feet. For irregular shapes, calculate sections separately. Depth should be average of shallow and deep ends.

5. Frequently Asked Questions (FAQ)

Q1: How do I calculate average depth?
A: Add the shallow end depth to the deep end depth, then divide by two. For example: (3ft + 6ft)/2 = 4.5ft average depth.

Q2: What if my pool isn't rectangular?
A: For circular pools, use π × radius² × depth × 28.32. For oval pools, use π × length/2 × width/2 × depth × 28.32.

Q3: Why is pool volume important for chemical treatment?
A: Chemical dosages are based on pool volume. Too little chemical won't be effective, while too much can be harmful.

Q4: How often should I recalculate my pool volume?
A: Only when you make significant changes to your pool's dimensions or shape.

Q5: What's the margin of error for this calculation?
A: With accurate measurements, the calculation is typically within 5% of actual volume. Irregular shapes may have higher margins.
