Thanks for clarifying that Jeff. I was confused by the little
arrows showing the air flowing backwards through the core.

Circulation is defined in terms of a line-integral about a line which
encircles the surface.  That's what the arrows indicate.

What do you get out of that integration David?
A net flow value? It looks like a distance times a Velocity.

Do you need a copy of this part of the book David?
I can scan a few pages in at a higher res and send them.
