Really? Um, LOL, OK.

300 cfm through a 1x2 port is less volume than a 300 cfm port at 2x4. That is twice the volume at the same cfm.:poke::realcrazy::rolleyes:

they can't have different volumes at the same CFM. CFM is the volume measurement. I think you mean the volume doubles at the same velocity.
