How do you figure the evaporation rate of water on a pond?

Answer 1

Im just guessing but, I would get a hold of a depth chart of the pond, find the average length, width, and height to get the ponds volume.

next get a couple of samples from different spots from the pond (there might be different concentrations of organic
and inorganic material based on the location...like if there are more dead leaves or duck/fish poop at one end). Thiis will effect the temp.

Take the combined samples, use one as a controlled indoor sample, and the next one leave outside. divide it into certain amounts, say 2 rectangular containers filled with the water. Make it so that the container is built to a smaller scale using the same ratios *** the lake. Record evaporation on both samples and from that you can do the math (solve for volume lost/time for the outdoor & indoor samples) Then scale the results up to find final volume evaporated at the pond's actual scale. This will give you the average evaporation rate. Hope this helps. Then you can try it over a span of the year to account for temp, different amounts of stuff in the water (the water being more dilute during spring and more concentrated in the winter. (making Ice wine is a good example of this)

Answer 2

I think if it is an irregular shaped pond with no controlled inflow and outflow you can't do it by observation. You could instead measure the temperature in the pond and the air and the relative humidity of the air above the pond. Compare them to charts of evaporation rates for pure water under conditions of those parameters to get a usable number per unit area of surface. The only tricky step after that is to estimate the surface area of the pond (maybe by scaling form a map of the region) to get the total evaporation.

Answer 3

the fee of evaporation is dependant on various components: (a million) Temperature of the water. the hotter it quite is, the quicker that's going to evaporate. At boiling element (a hundred stages celsius at sea point) it jumps to an incredibly severe fee of vaporization. Even frozen water will convert to a gasoline at a less expensive in a technique observed as sublimation. (2) Air rigidity. As air rigidity decreases, water will evaporate greater directly. that's why many nutrition applications have guidelines for preparation at sea point besides as bigger elevations (e.g. Denver that's a million mile in elevation). in case you have been camped on Mt. Everest, it would take you an incredibly little while to boil a pot of water. in the vacuum of area, water vaporizes very directly. in case you have been floating up there without secure practices, your blood would boil. Wind will help to improve the fee of evaporation because of the fact it has a tendency to decrease air rigidity in the vincinity of the region the place it quite is blowing, and that's going to additionally push away the air that has already soaked up water vapor on the water floor. (3) Humidity. On a damp, sticky day, water evaporates a lot greater slowly than whilst it quite is dry. (4) Water purity. some components whilst further to water will replace its boiling element and additionally the fee at which it evaporates. So i'd think of your terrific thank you to limit evaporation is to maintain the temperature low (making use of shade, and making the water point deep), and to attempt to safeguard it from wind. putting it on the part of a development or fence would help save the wind away. one element you are able to attempt is to characteristic something to the pond like lily pads (genuine or man made). The 0.33 link under includes information a pair of product observed as the pretend Lily Pad easy that floats on water. See final link for a place that sells residing lily pads.

Answer 4

it's the same as the evaporation rate of a glass(or saucer) of water placed in the same area get the surface area first.... just determine the volume of water and the surface area of the pond

Answer 5

That depends upon the size of the pond!

Answer 6

your question is so generic. haha. be more specific.

i bet this is for a project, huh?? haha
i'm gonna tell on you to your chemistry teacher
