I am an entry-level engineer. I have never doing any projects before. So I have a few problems.
1) After I calculate the loads, load of some room is small, only 4 or 5 inch flexible duct are enough. So can I use a 4 or 5 inch flexible ducts, then connect the duct to a 24*24 diffuser( diameter maybe 6 inch) ????
2) Most runouts diameters are 7 or 8 inches, so can I connect 7 inch flexible ducts to 8 inch diameter diffuser(24*24) through a transition? This is a similar question as question 1.
I really need your advice. I am waiting online.
Thanks a lot.
