Evaporation Formula:
| From: | To: |
Pool water evaporation is the natural process where water turns from liquid to vapor and escapes from the pool surface. Understanding evaporation rates helps pool owners manage water loss, chemical balance, and maintenance costs effectively.
The calculator uses the evaporation formula:
Where:
Explanation: The formula calculates daily water loss by converting surface area and evaporation rate into gallons using standard conversion factors.
Details: Accurate evaporation calculation helps pool owners determine normal water loss versus potential leaks, plan water refill schedules, maintain proper chemical balance, and estimate water costs.
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.
Q1: What is a normal evaporation rate for pools?
A: Normal evaporation rates range from 0.1 to 0.25 inches per day, depending on temperature, humidity, wind, and pool water temperature.
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: When should I suspect a leak instead of evaporation?
A: If water loss exceeds 0.25 inches per day consistently, or if you notice wet spots around the pool area, you may have a leak.
Q5: Does evaporation affect pool chemicals?
A: Yes, evaporation concentrates chemicals in the remaining water, requiring adjustment of chlorine, pH, and other chemical levels.
