1. What is Pool Evaporation Rate Calculation?

The pool evaporation rate calculation estimates daily water loss from a swimming pool due to evaporation. This helps pool owners understand water consumption and plan for refilling needs.

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

3. Importance of Evaporation Calculation

Details: Understanding evaporation rates helps in water conservation, proper pool maintenance scheduling, and identifying potential leaks versus normal water loss.

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 range from 0.1-0.25 inches per day, but can vary based on temperature, humidity, wind, and pool water temperature.

Q2: How can I measure my pool's evaporation rate?
A: Use a bucket test - place a bucket filled with pool water on the pool step and mark water levels. Compare evaporation in bucket versus pool over 24 hours.

Q3: Does pool cover reduce evaporation?
A: Yes, pool covers can reduce evaporation by 90-95%, significantly conserving water and reducing heating costs.

Q4: When is evaporation highest?
A: Evaporation increases with higher air temperature, lower humidity, higher wind speed, and when pool water is warmer than air temperature.

Q5: How does this help detect leaks?
A: If actual water loss exceeds calculated evaporation by more than 1/4 inch per day, you may have a leak that needs investigation.
