Water evaporation in swimming pools is a crucial factor in water loss and operating costs – learn how to calculate it precisely and reduce it effectively. With our detailed table and a handy calculator, you can accurately calculate the loss and save effectively with innovative products.
Swimming pool water evaporation: Evaporation table at a glance
Our detailed evaporation table allows you to precisely track how many liters of water evaporate per square meter, depending on temperature and wind speed. This enables a precise analysis and evaluation of pool water evaporation.
Clear table showing evaporation rates per m²
The following table shows the average hourly evaporation rates in liters per square meter for various temperature and wind speed combinations:
| Temperature | Calm (0-1 m/s) | Light wind (1-3 m/s) | Moderate wind (3-5 m/s) | Strong winds (5-8 m/s) |
|---|---|---|---|---|
| 10°C | 0,15 l/m²h | 0,20 l/m²h | 0,25 l/m²h | 0,35 l/m²h |
| 15°C | 0,20 l/m²h | 0,25 l/m²h | 0,35 l/m²h | 0,45 l/m²h |
| 20°C | 0,25 l/m²h | 0,35 l/m²h | 0,45 l/m²h | 0,60 l/m²h |
| 25°C | 0,30 l/m²h | 0,45 l/m²h | 0,60 l/m²h | 0,80 l/m²h |
| 30°C | 0,40 l/m²h | 0,55 l/m²h | 0,75 l/m²h | 1,00 l/m²h |
Temperature-dependent evaporation values
You can see that the evaporation rate increases significantly with rising temperature. At a water temperature of 10°C, for example, the loss is only 0,15 – 0,35 l/m²h, while at 30°C it can reach 0,40 – 1,00 l/m²h.
Influence of wind speed and humidity taken into account
Wind speed also has a significant influence on evaporation. The stronger the wind blows, the more water evaporates from the surface. Humidity also plays an important role: the drier the ambient air, the more water can pass into the atmosphere in the form of water vapor.
This will give you a clear overview of the actual water evaporation from your swimming pool. Read the next chapter to learn how you can easily implement this.
Formula for calculating water loss
Our simple formula lets you determine the actual water evaporation rate from your swimming pool in seconds. Simply enter the pool dimensions and relevant weather data.
Calculate the total loss in liters.
To determine the total loss of water through evaporation, use the following formula:
Evaporation (l/m²/day) x pool area (m²) x days per month/year = monthly/annual water loss (l)
You can use the evaporation values per square meter listed in our detailed evaporation table , which are based on temperature, wind speed and humidity.
Determine the monthly and annual costs
Based on the calculated water loss, you can now easily calculate the resulting costs. Multiply the total loss in liters by the current water rate in your region.
This will give you the average monthly and annual costs incurred due to evaporation loss in your swimming pool.
Compare different scenarios with each other
Our calculation formula allows you to compare different scenarios – such as the effects of changing weather conditions or the introduction of evaporation control systems like our Euro-Matic evaporation control spheres . This way, you can find the optimal solution for your swimming pool.
Familiarize yourself with our simple formula and quickly and accurately calculate your individual water loss. This creates transparency and planning security for your swimming pool management.
