Jan,

Your reply, once again, is loaded with errors and show very little
depth of understand of the very things you are discussing.

You say velocity cannot create low pressure. WRONG!! Just think of a
painter's spray gun. The paint is introduced into the air stream by
a low pressure created by the velocity of the air thru a venturi. A
hand pumped bug sprayer creates a low pressure by velocity over the
tip positioned in that high velocity steam. This is something you
have to come to terms with understand the workings of a sail

I asked you "What is the Ground effect have to do with a sail" you
elected to not answer that but you go off half cocked about wings,
sails, rudders, curved roofs etc all working the same. I AGAIN ASK
YOU to explain how ground effect is of importance in the operation of
a Sail?

Even in your use of Newton's Law your understanding is WRONG! You
say deflecting the air thus creating a force. Jan the air flow is the
FORCE. The deflecting is the action, which creates the reaction. Your
understanding of Newton's first law leaves at lot to be desired.

Jan, you better read some of those web sites you are calling up on
Search.

The Windsock seen at every airport and your beloved "Venturi Pipe" (
The Venturi effect" is very often misunderstood as the so called
"Bernoulli Effect"). It seems like The Bernoulli process always must
take place inside a Venturi Pipe! If not there will no "Effect".

The Ground Effect is just what physically happens in the Windsock and
in the Convergent Entrance Part of the Venturi Pipe! The longer into
the Venturi Pipe constriction we goes, the HIGHER TOTAL PRESSURE we
get and the lower airflow speed we get! Since you think that a sail
is some sort of half venturi pipe, you have the

Read all of PIMs exellent webpages!

You don´t need physical Sail explanations than that!

This webpage debunkes the false "Bernoulli Effect explanation" in the
painter's spray gun:

What, your ****?

And not checking the spelling before posting is the sort of sloppiness
you
abhor, isn't it?


Never once did I claim to abhor misspelling. I simply stated
that in a published work done at the college level one would
tend to doubt the credibility and accuracy of an author who
misspells the very topic upon which he expounds.

And, I did check the spelling with the spell checker but it
just so happens that both chord and cord are words
correctly spelled. What's your excuse for vis-a-vis?

I have a higher degree in English than you have in picking
your nose and since your finger goes up your nose all the
way to the third joint that's saying something.

Who are you?

Considering your overall spelling and reading comprehension, I'd say you
were still trying to get out of first grade, and nowhere near ready to
even think of going to college.
