1. What is Pool Evaporation?

Pool evaporation is the process where water turns from liquid to vapor and escapes from the pool surface. It's a natural phenomenon affected by temperature, humidity, wind speed, and pool surface area.

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 appropriate conversion factors.

3. Importance of Evaporation Calculation

Details: Understanding evaporation helps pool owners maintain proper water levels, conserve water, reduce chemical usage, and plan for regular refilling schedules.

4. Using the Calculator

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

5. Frequently Asked Questions (FAQ)

Q1: What is a typical evaporation rate for pools?
A: Average evaporation rates are 0.1-0.25 inches per day, but can vary based on temperature, humidity, and wind conditions.

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 oval pools: length × width × 0.8.

Q4: Does evaporation affect pool chemicals?
A: Yes, evaporation concentrates chemicals in the remaining water, requiring adjustment of chemical levels after refilling.

Q5: When is evaporation highest?
A: Evaporation peaks during hot, dry, windy days and is lowest during cool, humid, calm conditions.
