High Velocity Ductwork Sizing
High Velocity Ductwork Sizing
(OP)
Hi Folks
I am currently designing a high velocity ductwork system for distribution of air at (you've guessed it..)High Velocity. This is to transport hot air to drum jet or induction diffusers at high level in a warehouse for winter heating. The air might typically be at 30 to 45 degrees celsius.
I have merrily sized standard ductwork systems at velocities up to 10m/sec but I understand that when you get to the 15-20m/sec, the static regain method should be used.
It must be 25 years since I touched on this method and sadly my old college notes are somewhere in the attic, so is there anyone out there that can suggest a good source of information including static regain factors and a good worked example??
