Factors Affecting evaporation evaporation occurring in the water surface and the wet surface is a continuous movement. The amount of water vapor leaving the surface of the water, the air unit area properties on the (meteorological conditions), hocatec will vary according to water and environmental characteristics. These changes are occurring in the water with an energy effect. 1 gram of water vapor to become 539 to 597 calories of heat is needed. Evaporation; diffusion occurs by convection or wind action. The vapor pressure of the air in parallel continues until occurrence of diffusion of the water temperature drops below the saturated vapor pressure. hocatec When the water is warmer than the air convection (movement in the vertical direction) to start the movement. Factors affecting evaporation in the light of this evaluation can be summarized hocatec as follows. 1. Meteorological hocatec Factors
Radiation from the sun is the main source of heat. Decreasing hocatec or increasing the heat exchange is an important factor for the amount of evaporation. Amount of energy from the sun to the season, time of day and the weather varies depending on whether cloudy or clear. Radiation energy, but also the latitude varies according to the height and direction. b) Air Vapor Pressure:
Evaporation, the vapor pressure at the surface is proportional to the difference between the vapor pressure above the water. Water vapor pressure (ew), the air vapor pressure (ee) as long as it continues to evaporate large and EW = air vapor pressure when compared to the eye durur.b evaporation increases the amount of evaporation is reduced. c) Temperature:
The saturated vapor pressure of the evaporation rate is dependent upon temperature, influenced by a large amount of air and water temperatures. The daily and annual changes in evaporation, very similar to the daily and annual temperature variation. hocatec Minimal evaporation during the day in the morning, afternoon between 1200-1500 hours reaches hocatec the maximum value. Regarding still less evaporation temperature hocatec in the cold season is over in the hot season. d) Wind:
The water vapor diffusion and convection to keep evaporation must move away from the water surface. This movement of air (wind) possible. The higher the wind speed, hocatec the more evaporation. e) Pressure:
Air pressure increases the number of molecules in unit volume increases and decreases water evaporation will be raised again the possibility of returning to the air molecules bumping into the water splashed into the air molecules. However, this effect is minor compared to the others. As pressure decreases with height, it is worth noting that the evaporation in high places. 2. Geographical and Topographical Factors
