Evaporation Formula:
| From: | To: |
Pool water evaporation is the natural process where water molecules transition from liquid to vapor state due to environmental factors like temperature, humidity, and wind. Understanding evaporation helps pool owners manage water levels and maintenance schedules effectively.
The calculator uses the evaporation formula:
Where:
Explanation: The formula calculates daily water loss by converting the evaporation depth over the pool surface area into gallons.
Details: Accurate evaporation calculation helps pool owners determine water replacement needs, identify potential leaks, optimize chemical balancing, and reduce water waste and 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 swimming pools?
A: Normal evaporation rates range from 0.1 to 0.25 inches per day, depending on temperature, humidity, wind speed, 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 distinguish evaporation from a leak?
A: Perform the bucket test - place a bucket of water on pool steps and compare water loss between bucket and pool over 24 hours.
Q4: Does pool shape affect evaporation rate?
A: Surface area is the primary factor. Shape affects surface area calculation but not the evaporation rate per square foot.
Q5: When is evaporation highest?
A: Evaporation peaks during hot, dry, windy days when the difference between water and air temperature is greatest.
