	"Gasses"? Stay with me, I'm on a learning curve here.  I don't know
if it is important anymore between the "D" or "Square" shaped runners
anymore because it is only air going thru them.  I can understand air speed
in the runner, etc., but where it goes out the window for me is when you see
the runner, where it attaches to the plenum, is a square corner!  A lot of
plenum / runner combinations are shaped like a "T".  Believe me, I'm not
trying to make an issue out of this, just trying to understand and make the
best setup feasible.
	Thanks.....Tim.
