I am new to surface tension but I just read a description and I guess that makes sense. However, it would seem to me that evaporation would happen at a faster rate when there is more water in the air, because the water molecules in the body of water would have an attraction with the molecules in...
But in terms of say, a swamp cooler, the majority of the energy is coming from the air- which is the goal so that air temp drops right?
In terms of the effects of fan/air speed on the evaporation rate, my understanding is that it can have two effects:
1) the air (which has already had water...
Ok. So in terms of the evaporative-cooling process, heat is transferred from the air to the water, which gives the water the latent heat necessary for some of the molecules to break free and become vapor. Typically this results in a lower temperature air with higher relative humidity, and a...
So I also thought you needed a certain amount of external latent heat to turn liquid into vapor. But this latent heat can also come from the internal collisions of the molecules? Does the latent heat represent the energy needed to break through the barrier and become a vapor or for some sort of...
I have been reading a bunch of different explanations of evaporation- and now I am confused. Hopefully someone can help clear this up in my head so that I can sleep tonight. I am interested in what is happening at the molecular level as well. Let's take a look at a body of water.
In a body of...
I reference this forum all the time and you guys are always good at breaking down confusing questions so I decided I needed to make an account and get some help with a mental struggle I have been having for quite some time!
Two commonly discussed ways of improving a compressor's efficiency in a...
