e·vap·o·ra·tion

(ē-vap'ŏ-ra'shŭn),
1. A change from liquid to vapor form.
2. Loss of volume of a liquid by conversion into vapor.
Synonym(s): volatilization
[L. e, out, + vaporo, to emit vapor]

evaporation

[ivap′ərā′shən]
Etymology: L, ex + vapor, steam
the change of a substance from a liquid state to a gaseous state. The process of evaporation is hastened by an increase in temperature and a decrease in atmospheric pressure. See also boiling point. evaporate, v.

evaporation

the physical change when a liquid becomes a gas. Since such a change usually requires heat as an energy source, heat is drawn from the immediate environment, which produces a significant cooling effect. The size of the cooling effect depends on the latent heat of evaporation of the liquid. Evaporation of water is used by mammals in temperature regulation through sweating, and occurs in plants from the surface of the mesophyll cells during TRANSPIRATION.

evaporation

change of state from liquid to vapour form, achieved by absorption of latent heat from surroundings; characterized by cooling of surroundings and conversion of the liquid to vapour

evaporation (ē·vaˈ·p·rāˑ·shn),

n change of a liquid or a solid to a vapor or gaseous phase; does not form new substances, but the properties of the new phase may be different.

It is therefore beneficial to introduce some amount of solution subcooling so as to maximize sensible heat transfer from the earlier tube rows while still maintaining fully-wetted thin-film evaporation conditions on the bottommost rows.
Evaporation duct results from the rapid decrease of atmospheric moisture in the first few meters above sea level, which is quasi-permanent present and can increase signals above diffraction levels significantly for near surface propagation at frequencies of 1 GHz and above [1-3].
The problem has to do with the way of calculating a quantity called potential evaporation, the amount of evaporation that would occur given an unlimited water supply.
