The Slow Evaporation Of Water Normal Temperature Will Change Into. What this means is that gas or water vapors main way back into the water cycle is through evaporation which shows the significance of it. We understand this to be because of the molecular kinetics where the faster water molecules escape and become a part of the air.

The pressure in the evaporator is below atmospheric ie. They may think the water has disappeared or turned into air. If molecules are moving slow they bundle up and you get a solid.
The answer is yes the rate that water evaporates can indeed be calculated but it depends on a few more things than you mention.
Since those that escape have more energy than the average the process decreases the temperature of the water but how does. The fresh water generator or evaporator uses the heat from the main engines in the cooling water to produce fresh water from sea water. On a large passenger vessel the evaporators can produce 500 tonsday. Evaporation is the main pathway that water moves from the liquid back into the water cycle as water vaporThe Water Cycle.
