Given the same environment (air and water temps, humidity, air speed above), does the water level drop at different rates due to evaporation when comparing a large pond, small pond or even a 5-gal bucket?
In: Physics
The answers here are all wrong. You asked about water level. Evaporation depends on surface area. And water level also depends on surface area, since a wider area means a lower level. These two things exactly cancel out. Evaporation will affect both water levels the same.
Another way to think about it. Let’s say you have a pond and its water level drops by 1 mm per day. Now I construct a thin dam that divides it into two smaller ponds. Well the water is still evaporating the same from both sides (each a small pond), 1 mm per day.
