1. What is Pool Evaporation Rate?

The pool evaporation rate measures how much water is lost from a swimming pool due to evaporation. This calculation helps pool owners understand water loss patterns and manage water conservation effectively.

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 using standard conversion factors.

3. Importance of Evaporation Calculation

Details: Understanding evaporation rates helps in water conservation planning, determining refill schedules, identifying potential leaks, and optimizing pool maintenance routines.

4. Using the Calculator

Tips: Enter pool surface area in square feet and evaporation rate in inches per day. Both values must be positive numbers for accurate calculation.

5. Frequently Asked Questions (FAQ)

Q1: What is a typical evaporation rate for pools?
A: Typical evaporation rates range from 0.1 to 0.25 inches per day, depending on temperature, humidity, wind, and pool usage.

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: 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.

Q4: When is evaporation highest?
A: Evaporation peaks during hot, dry, windy days and when pool water temperature is significantly higher than air temperature.

Q5: How can I distinguish evaporation from leaks?
A: Conduct a bucket test - place a bucket of water on pool steps and compare water loss between bucket and pool over 24 hours.
