Bernie just re-iterates the conservation of energy rule: "All other things being equal, if the velocity increases, the pressure must decrease"
However, in our case the other things are not equal and the boundaries are badly defined.
So for solving nozzle problems bernie is tops, like why your boats bash together: when you approach one another and squeeze the water flow between, the pressure (water surface)must drop and so your hulls get sucked together. This also explains wave form drag and hull speed to some degree: as the water passes you it has to hurry up to squeeze past and the surface lowers (which makes the gap still smaller incidentally) forming the trough next to the boat.
Or why the jib helps the main - because it speeds up the flow in the slot, this air is lower pressure and fed to the back of the main.
However, a wing passing above the ground squeezes the air thu the gap, speeding it up and lowering its pressure, sucking the plane into the ground....huh...
Bernouli supports jetskis. Jetskis rely on the water being pumped thru a nozzle cone, and therefore having to speed up. The lowered pressure acts on the cones walls and pulls the cone forward. The cone is attached to the jetski, which in turn is typically attached loosely to a moron. Bernouli is responsible for the increase of velocity of morons. Tell your lawyer.
