I had a DUH! moment this morning. For a couple of years now I have been figuring cross sectional area using pi and algebraic formulas. For the last month I have been trying to teach these formulas and methods to people that hardly read and write.

I sat down this morning and reduced the equations to one simple method:

For round to square: Diameter x 0.885 = length of sides of the square.

For square to round: length of side of square / 0.885 = diameter.

Nice and simple, I like it. Here's a wrench in your works....Peter has me thinking the we should just be going 1:1 square to round since the corners of the square are tied up with laminar flow and the useable space is basically the circle contained within the square. I haven't quite adopted this throughout my builds yet, but it does make sense and it's how he figures his geometry so it obviously works. Nice formula though!

Hmmm. Interesting. I can't say that I've seen anything that would make me disagree.

Funny thing is, I often wonder if it matters at all, as these things seem to just work anyway. I am often choking back the feed and the horizontal sections on top of a cook stove are often every shape and size imaginable. Even choking these back farther from the riser seems to help conduct heat to the pots. Though, they are all so crude that the differences are hardly realized.
