Transport Velocity of Water
Transport Velocity of Water
(OP)
I have a process exhaust that needs to move moist air. Part of the duct system is horizontal, and part is a straight vertical run. I want the water droplets to move with the air, and not run down the inside of the duct wall. What would my minimum transport velocity need to be? I know that I could overkill and get it to work, but I'd rather have some good design numbers to start out with.

RE: Transport Velocity of Water
I suggest you get help from Perry (Chem. Eng. Handbook). It gives "ballpark" figures on gas velocities, as well as maps in which different flow régimes (and mist flow in particular) appear as functions of mass ratios, etc.
