The calculation of heat of evaporation of Urmia lake water



In order to study the heat effect of mixing of fresh waters (winter rains in the form of floods) with urmia lake water, the heats of mixing of urmia lake water with distilled water at 25ºC have been measured. On the basis of these experimental data, the Heats of dilution of fresh water in urmia lake water and urmia lake water in fresh water have been calculated. By considering the isothermal cycle of the dilution of urmia lake water, the partial heat of evaporation of water from urmia lake water was found to be ca. 2443.58 at 25ºC.
