People are mistaking Back Pressure with resistance to flow.
If you want to use that term, not a problem. I guess it is just easier to say "Back Pressure" than resistance to flow.
Back pressure (resistance to flow) is bad. Yery simple.
Maybe the "Back Pressure" people are talking about is the 14.7 lbs at sea level.
