How to saturate air with water vapor ?

Question

I need to saturate a small tank for an experiment, so that the materials do not evaportate their water into air (which is at ambient temperature, by the way). How would you do that in a simple way ? Thanks

Answer 1

Bubble air through water using an aquarium pump. You may place the air pump within the container so as to recirculate the air.

Also be aware that at high humidity the temperature will be critical with respect to dew point. Keep the chamber at a constant temperature to minimize condensate formation. Otherwise you may find condensation forming on the inside of the container wall if the outside temp drops below the insides dew point temperature. This condensation will collect on the bottom of the bottom of the container and could pose a problem.


You may find that just having an open container of water in the container may be enough added humidity to suit your purpose without the need to bubble air through water.

Answer 2

You can buy misting nozzles that will spray a very fine mist into the tank.

Or if availabe, and temperature is not a concern, add a little bit of steam to the tank

Answer 3

the saturated air whilst cooled,consequences interior the shortcoming of water content interior the air.or we are in a position to assert that the water preserving ability of the air decreases.this consequences interior the formation of dew from the water vapour before latest interior the air.the temprature the place the 1st drop of dew is shaped is stated as the dew element temprature. hence the water vapour latest interior the air condenses and types dew.
