1. What is Swimming Pool Evaporation?

Swimming pool evaporation is the natural process where water turns from liquid to vapor and escapes from the pool surface. It's a significant factor in water loss and maintenance requirements for pool owners.

2. How Does the Calculator Work?

The calculator uses the evaporation formula:

Where:

• \( SA \) — Surface area of the pool (square feet)
• \( ER \) — Evaporation rate (inches per day)
• \( 7.48 \) — Conversion factor (gallons per cubic foot)
• \( 12 \) — Conversion factor (inches to feet)

Explanation: The formula calculates daily water loss by converting surface area and evaporation rate into gallons, accounting for unit conversions.

3. Importance of Evaporation Calculation

Details: Understanding evaporation rates helps pool owners manage water conservation, reduce refill costs, maintain proper chemical balance, and plan maintenance schedules effectively.

4. Using the Calculator

Tips: Enter pool surface area in square feet and typical evaporation rate in inches per day. Common evaporation rates range from 0.1 to 0.25 inches per day depending on climate conditions.

5. Frequently Asked Questions (FAQ)

Q1: What factors affect pool evaporation rates?
A: Temperature, humidity, wind speed, pool water temperature, and air movement significantly impact evaporation rates.

Q2: How can I reduce pool evaporation?
A: Using pool covers, reducing water temperature, installing windbreaks, and maintaining proper chemical balance can minimize evaporation.

Q3: What is a typical evaporation rate for pools?
A: Typically 0.1-0.25 inches per day, but can be higher in hot, dry, windy conditions and lower in cool, humid conditions.

Q4: How do I measure my pool's surface area?
A: For rectangular pools: length × width. For circular pools: π × radius². For irregular shapes, consult pool specifications or use online calculators.

Q5: Does evaporation affect pool chemistry?
A: Yes, evaporation concentrates chemicals in the remaining water, requiring adjustments to maintain proper balance.
