I am trying to define a mass flow controller for a customer who wants to use different gases through it. He gave me the units in CFM so I converted them to LPM which is what Mass flow controllers use for their specs. However I am not sure if using the convert table supplied here is for air and then I would have to use the gases K value to modify the LPM for that particular gas. Are the values supplied in this chart for air?
Thnaks much!!
