WebEvaporation rates, which are provided by meteorological stations, are found by measuring and recording water losses by evaporation over many years. Evaporation rates are usually expressed as the water depth lost in millimetres over a period of time, e.g., 2 mm/day, 14 mm/week or 60 mm/month.

WebEvaporation will vary with wind and temperature. It should be measured daily, and the pan should be kept well filled. Lagoon evaporation rates are invariably less than pan evaporation rates. Pan correction factors generally vary from 0.7 to 0.9. The larger the lagoon, the more its evaporation rate lags behind pan evaporation, so the smaller

Evaporation is a type of vaporization that occurs on the surface of a liquid as it changes into the gas phase. High concentration of the evaporating substance in the surrounding gas significantly slows down evaporation, such as when humidity affects rate of evaporation of water. When the molecules of the liquid collide, they transfer energy to each other based on how they collide.
