1. What is Swimming Pool Evaporation Rate?

The swimming pool evaporation rate measures how much water is lost from a pool due to evaporation. It's calculated based on the pool's surface area and the daily evaporation rate, converted to gallons per day for practical water 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 surface area by evaporation depth, then converts cubic feet to gallons.

3. Importance of Evaporation Rate Calculation

Details: Understanding evaporation rates helps pool owners manage water loss, plan refilling schedules, optimize chemical balancing, and implement water conservation strategies.

4. Using the Calculator

Tips: Enter pool surface area in square feet and daily evaporation rate in inches. 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 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 for pools?
A: Most pools lose 1/4 to 1/2 inch of water per day, but this varies greatly with climate and season.

Q4: How do I measure my pool's actual evaporation rate?
A: Use a bucket test - place a bucket filled with pool water on the pool step and compare water loss between bucket and pool over 24 hours.

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