Bernoulli's principle states that as the speed of a fluid increases, its pressure decreases. This can create a force, known as Bernoulli's force, that can lift objects (like airplane wings) or propel them forward (like sailboats). It is the principle behind how airplanes generate lift and how sails harness the wind for propulsion.

What country is bernoulli from?
Daniel Bernoulli was a Swiss mathematician and physicist. He was born in the Republic of Geneva in 1700.
How does Bernoulli and principle explain how wind can take the roof off a house?
The Bernoulli principle states that as wind flows over a roof, the pressure is lower above the roof compared to below it. This pressure difference creates lift, which can exert an upward force on the roof. If the force of the wind exceeds the strength of the roof's structure, it can cause the roof to lift off the house.
Who discovered the Bernoulli Effect?
The Bernoulli Effect was discovered by Daniel Bernoulli, a Swiss mathematician and physicist, in the 18th century. He observed that an increase in the speed of a fluid is accompanied by a decrease in pressure.
How does the bernoulli's principle affect a biplane?
The Bernoulli's principle states that as the speed of a fluid (air) increases, its pressure decreases. In a biplane, the wing design creates a pressure difference above and below the wings, generating lift. This lift force helps the biplane overcome gravity and fly.
Which explains the downward force produced when air flows over the winglike spoiler on a car race?
The downward force on a winglike spoiler is generated due to the Bernoulli principle and the Coanda effect. As air flows over the curved shape of the spoiler, it creates a region of low pressure above the spoiler and high pressure below it, resulting in a net downward force. This force helps increase traction and stability at high speeds, improving the car's handling on the track.

Bernoulli's equation and an airplane's wing?
Bernoulli's equations explain 100% of the lifting force created by wings. But Newton's third law also explains 100% of the lifting force. This should not be suprising, since Bernoulli's equations are based on Newton's laws. Bernoulli and Newton are two different ways of explaining a complicated situation. Neither is more "right" than the other. If we choose one explanation while ignoring the other, then our understanding of flight will be incomplete. To be clearer... Bernoulli's equation describes the lifting force in terms of pressures applied to the wing surface. There are no other forces involved. If we know the pattern of pressures, then we know the lifting force. Yet the explanation of flight remains incomplete. Wings feel pressure because they change the motion of the surrounding "parcels" of air, and air has mass. If a wing applies a force which causes air to accelerate downwards, then by Newton's 2nd and 3rd laws, the wing must experience an equal upwards lifting force. If we know the acceleration of the air surrounding the wing, then we know the lifting force.
Why does air travel faster above an airfoil?
Because the path it takes is longer. This is the Bernoulli effect. Be aware that the small amount of upward force from the Bernoulli effect IS NOT the principal force that allows an aircraft to fly. Be aware that the explanations you read in most textbooks ARE NOT the correct explanations for aerofoil lift. To prove this is so, your task is to explain how an aircraft can fly inverted. According to the "Bernoulli effect" explanation, the aircraft should plummet towards the ground at an acceleration of 2g.
