1. What is Pool Water Evaporation?

Pool water evaporation is the natural process where water molecules transition from liquid to vapor state due to environmental factors like temperature, humidity, and wind. Understanding evaporation rates helps in proper pool maintenance and water conservation.

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: Accurate evaporation calculation helps pool owners maintain proper water levels, plan for water replacement, conserve resources, and identify potential leaks by distinguishing normal evaporation from abnormal water loss.

4. Using the Calculator

Tips: Measure your pool's surface area accurately. Typical evaporation rates range from 0.1 to 0.25 inches per day depending on climate conditions. Both values must be positive numbers.

5. Frequently Asked Questions (FAQ)

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

Q2: How can I reduce pool evaporation?
A: Use pool covers, reduce water temperature, install windbreaks, and maintain proper chemical balance to minimize evaporation.

Q3: What is a typical evaporation rate?
A: In moderate climates, expect 0.1-0.25 inches per day. In hot, dry, windy conditions, rates can exceed 0.5 inches daily.

Q4: How do I distinguish evaporation from leaks?
A: Perform the bucket test - place a bucket of water on pool steps and compare water loss between bucket and pool over 24-48 hours.

Q5: When is evaporation highest?
A: During summer months, especially on hot, dry, windy days with low humidity and significant temperature differences between water and air.
