Bernoulli's Principle

"In fluid dynamics, Bernoulli's principle states that for an inviscid flow, an
increase in the speed of the fluid occurs simultaneously with a decrease in
pressure or a decrease in the fluid's potential energy." Devices can be made
based on this principle to create low pressure areas, to draw a fluid to a
chosen area. Pilot tubes are used on aircraft to determine the flight speed.
The equation is also used to determine the flow of water from a draining tank.
With many more uses applied in flight, sailing, an yet more to be discovered!
