Geez, sounds like a meteorology question....maybe some weather person can give you an answer. My guess would that it would have to entail the temp of the water versus the temp of the air to give you a rate of evaporation. Then wind speed needs to be taken into account and if it is sunny or cloudy and maybe barometric pressure....why do want to know this by the way?
Well, I guess I could just get a probe or something...just thought a formula might be more fun.
I'm actually trying to figure out what the humidity would be an inch or two above the water surface of a tray of water. PinguiculaMan grows his plants in a tray system 24/7/365. I'm just trying to figure out where the break may be in humidity for which plants I can just stick in a tray of water, and which ones should be in a terrarium.

From what I understand, he hardens off all his plants so it doesn't matter what the conventional meathoid of growing is. (sort of along the lines of how I grow dark VFTs when needed)But, I don't know if he has any northern or tropical pitchure plants which usually require humidity for maintaning their traps.
As to a formula, you have to take into account tempurature and air movement, but if you really want some numbers, I actually have some, lol. *stop looking at me like that, it's from my chem class okay*. I'd rather not have to go dig out my notes, but I can if you still need them.

No, I got a humidifier. It seems to work well, it is only the second day though.
