i am trying to calculate how much water i need to raise air humidity for condensate to apear. i use formula from psychrometric chart :

humidity ratio g/kg * volume(m3)/volume m3/kg = volume of water needed.

(18-15)*0.032/0.86=0.112g

so as i understand i need 0.112g of water to evaporate for condensate to apear.

then i tryed looking for formula to calculate how fast water evaporates in my given situation (water temp 24 celcius, vind speed 1-3m/s, area of water 0.16 m2, room temp 23 celcius, room relative humidity 60-85), and i faild... can anyone give me a hand with this one?

i am trying to calculate how much time do i have for water level in my aquarium to reach critical point.

thanks.
