In looking thru this section, I was reminded of some basics (one of which is that I am NOT a fluid dynamicist!): The pressure drop thru round and circular ducts of the same cross-sectional area is NOT the same. to make sure we're BOTH using this WONDERFUL, time-saving tool properly and to be sure of my "faith" in it!)
