how do you figure out what size vents/ducts to put in?
I have limited space and bought a 6" flex duct tube and a 10x6 register to see if it would fit where I want it to go. It'll fit just fine. So the question is how much flow do you get from this size duct?
I have NO central air and wanted to at least get the vents in place now that I have the roof mostly off.
Am I looking at this the wrong way? For example, if I use 6" duct through out the house, then if 1 room is twice the size of the others, just have 2 ducts in there.
Or is this more of using baffles/limiters to restrict flow to some to get more to others?
