Haihtumisnopeuden
Haihtumisnopeuden is a term primarily used in Finnish hydrology and environmental science to denote the rate at which water evaporates from a given surface. It is typically expressed in units of volume per time, such as liters per hour per square meter (L h⁻¹ m⁻²) or millimeters per day (mm d⁻¹). The concept is closely related to evaporation but specifically emphasizes the kinetic aspect of the process—how quickly water molecules transition from the liquid phase into the vapor phase under specific environmental conditions.
The measurement of haihtumisnopeuden involves both direct and indirect methods. Direct methods include the use of
In practice, haihtumisnopeuden is applied in irrigation management, where knowing the evaporation rate helps determine optimal
The term is largely confined to Finnish literature and scientific literature translated into Finnish. In international
