Yes, a somewhat simplistic article, but I believe, that was the intent of its' author. It seems mostly concerned with the understanding of flow sums thru simple tubing, with a goal of establishing the flow volume vs. diameters, and perhaps to spark some basic insight as to one's true requirements.

As far as the math, I believe the author is calculating the approximate area available based on the fact that the dimensional nomenclature for such tubing is referencing O.D. dimension not I.D..
