Oooops!!! 
For the benefit of others we were discussing Bernoulli's theorem, FB claimed it was how a water pistol worked, I thought blah blah blah..........
(anyway it was a serious general question, honest!!!)

Disco is right, Bernoulli's theorem was concerned about the pressue on curved surfaces and how air would travel slower over the curved surface and therefore create lift witht he faster flow traveling over the under side and flat wing surface.
It is also the theorem that was used when building the Humber Bridge. To avoid problems when wind would hit the bridge deck the underside of the deck is curved. This has the effect of pulling the deck down and stabalising it. Kind of a good idea on a suspension bridge that is a mile long between the two pillars.The only reason it is ever closed, due to wind, is top stop lorries and cars beiong blown over or off the bridge!
