Answer:
In fluid dynamics, Bernoulli's principle states that an increase in the speed of a fluid occurs simultaneously with a decrease in static pressure or a decrease in the fluid's potential energy.
APPLICATIONS :
Moving Boats in Parallel
Whenever two boats are moving side by side in a similar direction, then the air or water will be there in between that moves quicker compare with when the boats are on the remote sides. So according to Bernoulli’s theorem, the force between them will be decreased. Therefore because of the change in pressure, the boats are pulled in the direction of each other due to attraction.
Airplane
Airplane works on the principle of Bernoulli’s theorem. The wings of the plane have a specific shape. When the plane moves, the air flows over it with a high speed as contrasted with its low surface wig. Because of Bernoulli’s principle, there is a difference in the flow of air above & below the wings. So this principle creates a change in pressure because of the flow of air on the up surface of the wing. If the force is high than the mass of the plane, then the plane will rise.
