return air general questions


Alright just some general education questions for me to undestand better why things are done certain ways

1) Shouldn't the return velocity be lower then the supply? wouldn't a lower velocity help make the filter system work better and not pull smaller particles forcefully through the filter?


2) Why are return trunks generally smaller then the supply plenum's total area? wouldn't you want to follow something like I asked about in #1?


if these are correct or good ideas, why does it seem like returns always have such a small total square area?

because somewhere along the line. installers started to think that since the return is a negative pressure, it does have as much of a resistance to flow in the return duct.
