1. What is Swimming Pool Water Evaporation Rate?

The swimming pool water evaporation rate calculates how much water is lost from a pool due to evaporation. This is important for water conservation, chemical balance maintenance, and proper pool management.

2. How Does the Calculator Work?

The calculator uses the evaporation rate 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 the volume of water evaporated by multiplying the surface area by the evaporation depth, then converts to gallons.

3. Importance of Evaporation Rate Calculation

Details: Understanding evaporation rates helps pool owners maintain proper water levels, reduce water waste, maintain chemical balance, and plan for water replacement needs.

4. Using the Calculator

Tips: Enter the pool's surface area in square feet and the estimated 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 factors affect pool evaporation rates?
A: Temperature, humidity, wind speed, pool water temperature, and air movement all significantly impact evaporation rates.

Q2: What is a typical evaporation rate for pools?
A: Most pools lose 0.1-0.25 inches of water per day, but this can vary greatly with weather conditions and pool usage.

Q3: How can I reduce pool water evaporation?
A: Using pool covers, reducing water temperature, installing windbreaks, and maintaining proper chemical balance can help reduce evaporation.

Q4: 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.

Q5: When is evaporation highest?
A: Evaporation is typically highest during hot, dry, windy days when the water temperature is warmer than the air temperature.
