Control of RH and Temp of Air

  1. Sep 20, 2012 #1

    I am trying to provide a humid air stream along some ¼” tubing, where I can roughly control the relative humidity and temperature, this doesn't need to be exact.

    I already have a compressed air tank, regulator and flow meter to provide the correct flow rate.

    I need to find out whether bubbling air through water will result in 100% relative humidity and whether or not this depends on the the amount of water it is bubbled through?

    If so I can heat the water to get the right amount of moisture in the air at 100% humidity and then heat the air further in the outlet pipe in order to lower the humidity to the level I require.

    Please excuse my ignorance as I do not have an extensive knowledge of this subject, any help or guidance you can give me will be greatly appreciated.
