I=3D92ve enjoyed the recent interchange and discussion
on the subject of =3D93Venturi=3D94 apertures as related to the
=3D93double Venturi=3D94 design on the Minnesota Flat Top.
I hesitate to add to the discussion and further confound
the issue other than to thank those who initiated the exchange
allowing those interested to understand how the =3D93DV=3D94 works so they =
decide whether to try it or not.
Special thanks to John Britt for raising the question and to James Freeman =
for his comprehensive explanation (vena contracta... sounds so sexy). Book =
sales are spiking and I like that.
