Would a rectangular duct with the same volume and cross section as a round duct - flow air the same? I was contemplating using a 24" x 2.5" x 20" rectangle duct in placement of a 8" x 24" duct
Thanks... I thought it would not work.
any ideas on different materials for a 8" duct? not a fan of the big box store duct work they have since they are flimsy. I know I can buy thin wall tubing but trying to find a cheaper way
Can two exhaust pipes be used?
How would one calculate the diameter and length needed for two exhausts?
How would one calculate the size of each plenum?
One 8" would have been 23" according to the Feldon Calculator for my application -anything less in diameter would be too tall.
