Example
A basin with the following dimensions (100 m length x 30 m width x 1 m depth) contains 3,000 m³ of water. In sunshine 3 m³ evaporates per hour with the help of our E46 (makes 1 mm of water).
Result:
In one day with 10 hours of sunshine, approx. 50 m³ evaporates ((3 m³ x 10) + (1.4 m³ x 14)); this results in 16.67 mm per day.
