Evaporative coolers (i.e., "Swamp Coolers") work by having water put onto a surface and then blowing air over it so that it evaporates; the equilibrium temperature of this action is the Adiabatic Saturation Temperature or "Wet Bulb" temperature. In a high humidity environment, the wet-bulb...
This is why relative humidity can be low even in places that are relatively humid during warmer seasons. When air cools, its capacity to hold water vapor decreases, often leading to condensation if the air is saturated. Evaporative cooling is a process that takes advantage of this principle. ...
Evaporative Cooling Offering a more environmentally friendly cooling method than others, evaporative cooling uses the natural process of evaporation to cool the air before it’s circulated through the data center. This becomes even more effective in areas with low humidity and dry climates. How it ...
Theoretically, yes, wiping sweat off the body would remove the fluid before it evaporates, and main benefit of sweat is evaporative cooling. However, you’re sweating all over your body and probably only wiping sweat off a small percentage of your skin (like your face). As such, I wouldn...
