Evaporation: Distribution How do you speed up evaporation?
6
Evaporation Factors: 1. Pressure 2. Surface Area 3. Tempreture of Substance 4. Density 5. Concetration of Subtrance Evaporating in the Air 6. Flow rate of air
Solving These Factors: Pressure: Pool the water to large shallow catchment areas keeping the molecules together Surface Area: Large surface area allowing the water too pool and evaporate faster allowing more surface molecules to escape Temperature of Substance: Heat up the water by having large open spaces in the north area, allowing the daylight sun to heat then water, which can then be transered to seperate pooling areas underground, heating the water thermally. Density: The higher you heat the water, the lower the density of it goes, therefore heating up the water will give a lower density and a faster evaporation. For example water at 4 degrees has a density of 999.9730kg/m3 compared to water at 100 degrees celsius that has a density of 958.4kg/m3 Concentration of Substance in Air: clensing the air around with plants Flow Rate of Air: Catching fresh air from the south that normally blows in a northerly direction using dark concrete walls that attract sunlight that is pushed onto the water, having fresh air blow over the water surface encourages evaporation.

Materials That Encourage Evaporation
Evaporation: Distribution Advection Fog
10
Advection is caused by the movement of a mass of air across the earth’s surface. Such a fog may occur at any time of day and sometimes covers a very large area. Most advection fog develops when warm, moist air rides in over a cold surface—land, ice, or water. A large volume of air is cooled below its dew point, forming a thick blanket of fog that may persist for days, drifting with the wind. Advection fog often develops along seacoasts where warm air comes in contact with cold ocean currents. Noted foggy regions include parts of North and South America’s Pacific coast and the coasts of the northeastern United States, the Atlantic Provinces of Canada, and northwestern Europe. Sometimes advection fog is formed when a mass of air is forced across rising terrain, such as the slope of a mountain. As the air reaches greater elevations, its pressure decreases. The drop in pressure produces a phenomenon called adiabatic cooling, which may sufficiently cool the air to cause its water vapor to begin to condense. Fog that develops in this manner is called upslope fog. Evaporation Fog occurs when the amount of moisture in the air is increased beyond the saturation point by the evaporation of water that is warmer than the air. This process is similar to the condensation of steam rising from a teakettle. Evaporation fog sometimes forms in irregular columns rising from the surface of water; such fog is commonly called steam fog.

Salt or Fresh Water? Question: -------------------------------------------------------------------------------We just did a 2 week experiment on evaporation of fresh versus salt water and the fresh water (from the tap) evaporated more than the salt (from the ocean) water? We kept the two bottles side by side in a room with a constant temperature of 82 degrees and 47% humidity (air conditioning) and kept the temperature gauge next to it to ensure that. What is the reason that the FRESH water evaporated more?
-------------------------------------------------------------------------------Replies: -------------------------------------------------------------------------------Think of the water as a crowd. The fresh water is a crowd of people with no boundaries, and the salt water is a crowd of people surrounded by a bunch of poles. If you want to get out of the crowd, it is easier if you are in the fresh water because there is nothing blocking you. In the salt water, you have to navigate through people and avoid poles, so it takes longer to get out of the crowd. The salt “gets in the way” of water molecules trying to evaporate, so the fresh water evaporates more than the salt water. (this example is not exactly scientifically accurate -- because the salt can move around but poles can’t, but the basic idea is what I am going for, here) Also, imagine if the poles had delicious foods on them. The crowd would tend to cluster around the poles. The closer together the poles are (or the more salt there is), the less space there is for people to move through. Water “likes” salt -- salt dissolves easily in water -- in contrast, things like oil or peanuts or rocks do not dissolve easily. Individual “pieces” of water (the smallest piece of water possible is called a “molecule”) tend to cluster around salt molecules. Some water is not near a salt molecule, so it is in its normal state. As the water evaporates, the salt stays there. (do not forget: tap water has salt too, just not as much). The concentration of the salt goes up as it evaporates, which is like having the poles get closer and closer together. The more salt there is for a given amount of water (this is called ‘concentration’), the less evaporation can occur. So, the salt water will evaporate more slowly and more slowly the longer you let it sit there. Because there is less salt in the tap water, tap water stays evaporating at a higher rate for longer. So there are two reasons why the salt water evaporates more slowly! I hope this helps, Burr Zimmerman

Dense Evaporation After water is heated in catchment pools near the Williamstown piers it is moved through to this space, where people experience heated water being cooled by wind creating an almost morning fogged space, where one can see evaporation.

Heating Water Once collecting the water, it is heated in a large space over various catchment pools. This water is further transfered in to more catchments in the south where a more feirce evaporation process is taking place.
