Daniel Bernoulli (1700-1782)


Bernoulli was a Swiss doctor and mathematician. He showed that when the speed of a liquid increases, the pressure of the liquid drops.
In the same way air , flows faster over the curved upper surface of an aircraft wing than the air passing under the flatter lower surface.
This means that the air pressure below the wing is greater than the pressure above,which creates an upward lift.
