Evaporation Formula:
| From: | To: |
Pool water evaporation is the natural process where water molecules transition from liquid to vapor state due to heat energy. This occurs continuously in swimming pools and is influenced by factors such as temperature, humidity, wind speed, and pool surface area.
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 volume measurements.
Details: Understanding evaporation rates helps pool owners manage water conservation, plan refill schedules, estimate water costs, and maintain proper chemical balance in the pool.
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 factors affect pool evaporation rates?
A: Temperature differences between water and air, humidity levels, wind speed, pool water temperature, and pool usage all influence evaporation rates.
Q2: How can I reduce pool evaporation?
A: Use pool covers when not in use, reduce water temperature, install windbreaks, and maintain proper chemical balance to minimize evaporation.
Q3: What is a typical evaporation rate for pools?
A: In moderate climates, typical rates are 0.1-0.25 inches per day. In hot, dry climates with wind, rates can exceed 0.5 inches per day.
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 measure the water level difference between the bucket and pool over 24 hours.
Q5: Does evaporation affect pool chemistry?
A: Yes, evaporation concentrates chemicals and minerals in the water, requiring adjustment of chlorine, pH, and other chemical levels.
