If the same lump of air that was split at the leading edge is
reconstituted
at the trailing edge, then those molecules that passed around the outer
surface 100mm away *must* have travelled faster than those that passed
the
inner surface 100mm distant.
And that's where your theory falls down!
You assume that the air is some kind of lego block toy that has a
fixed structure and that after passing over the foil it must once
again lock back into that same structure.
That bit isn't a theory, it's a qualified proposition.
If that were so how would you explain turbulence and vortices
Summink to wiv fings gettng in the way.
