What principle relates the speed of a fluid and its pressure and helps describe the flow around a wing?
Correct answer Bernoulli's principle
Fact
Did you know?
A wing produces lift by creating a pressure distribution and deflecting a mass of air downward. Its shape, its angle of attack and the circulation of the flow are determining factors. Bernoulli's principle links, under certain conditions, the speed of a fluid to its pressure and helps to describe the differences observed around the wing. Newton's laws in parallel describe the forces associated with the change in momentum of air. These explanations are not rivals: they describe compatible aspects of the same phenomenon. To say that “Bernoulli alone makes the plane fly” ignores the complexity of aerodynamics and the effects of angle of attack.
