Bernoulli's principle says that air moving faster over the top of the wing is of lower pressure. The difference in the speed of the airflow between the top and bottom of the wing is due to the difference in "chord" length of the wing top and bottom. The classical wing shape has a longer chord over the top of the wing than the bottom. So the air must move faster over the top than the bottom. The difference in speed creates a difference in pressure. This pressure difference "sucks" the airplane up into the sky. Problem is...it isn't true, or at least it isn't the only factor causing lift. In particular, if this was the only thing causing lift then it would be impossible for a plane to fly upside down since the long chord of the wing would be on the bottom and the pressure difference would "suck" the plane downward. Most planes can indeed fly upside down. One possible reason why an airplane might not be able to fly upside down is whether or not the airframe was designed for the wing to be loaded upside down. A 707 has been flown upside down, so very large aircraft not specifically designed for aerobatics can indeed be flown upside down. Furthermore, not all aircraft wings even have unequal chords. Indeed, the Wright flyer's wing had equal chords. Most paper airplanes have wings with equal chords. The low pressure is insufficient to lift the airplane. Instead the airplane lifts primarily because the wings thrust a large amount of air downward as it passes the wing. Newton's third law. This thrust (lift) only occurs when the leading edge of the wing is above the trailing edge. If the plane is flown upside down then, as long as the leading edge is higher than the trailing edge, the air is still thrust downwards and the plane still lifts. This can be easily shown with a piece of stiff flat (equal top and bottom chords) cardboard held out the window of a moving car. If the front edge is above the trailing edge then the cardboard is forced upwards. If the front edge is below the trailing edge the cardboard is forced downwards. It is humorous that airplanes have been flying for over a century, but many students are still taught a completely bogus explanation, involving just the Bernoulli principle, for the phenomenon. The above answer does not 100% explain the behavior of a wing. Other factors, including Bernoulli's principle also contribute. The balance between the importance of say downward thrust of the air flow, the Bernoulli principle, drag, normal operation speed, normal operation altitude, wing strength, weight and a host of other factors control the optimal wing shape for a given aircraft. If you look at fighter aircraft which have a thinner wing design and that of a commercial 747 which have a much thicker wing design, which one would have the greater lift capacity? Which one is designed for speeds of 300-400 MPH versus supersonic flight (up to perhaps Mach 2)? Which one is designed for aerobatic maneuvers? What is the relationship between the thrust of the engines and the weight of the aircraft? Those factors, and many others, have a large affect on the optimal wing shape for a particular aircraft.

Which of the following does Bernoullis principle help to explain?

Bernoulli's principle helps to explain how the speed of a fluid (such as air or water) is related to its pressure. It is commonly used to understand phenomena like lift in aircraft wings, the flow of fluids through pipes, and the operation of carburetors and atomizers.


Why is an airplane able to fly because of bernoullis principal?

That's "principle", not "principal". The idea is that the airplane's wings are shaped in such a way that the air moves faster on the top than on the bottom. As a result - and applying Bernoulli's principle - there is less pressure on the top of the wings.


What is Bernoullis principle and explain?

Bernoulli's principle states that as the speed of a fluid (such as air or water) increases, its pressure decreases. This principle is based on the conservation of energy in a fluid flow system, where the total energy remains constant between pressure energy, kinetic energy, and potential energy. It is commonly used to explain phenomena such as lift in aircraft wings and the flow of fluids through pipes.


Explain in detail what Bernoullis Principle is?

§ Like a airplane wing, at the top it is curved, and that creates longer distance from front to back then the straight bottom. This causes the air on top to travel farther and thus faster to reach the back, then the air underneath, is creating a difference in pressure between two surfaces


Bernoullis principle states that the faster a fluid moves the less pressure the fluid exerts?

Yes, Bernoulli's principle states that as the speed of a fluid increases, the pressure exerted by the fluid decreases. This principle is based on the conservation of energy in a flowing fluid. It is commonly observed in applications such as airplane wings, where faster-moving air creates lower pressure and generates lift.


In According to Bernoulli's principle what characteristic of a moving fluid determines its pressure?

The speed of the moving fluid determines its pressure according to Bernoulli's principle. As the speed of the fluid increases, the pressure decreases, and vice versa. This principle helps explain how lift is generated in airplane wings.


How does an airplane get lift during take off?

As the airplane speeds up the air flowing around the control surfaces speeds up as well. When this happens the horizontal stabilizer is deflected into the wind causing the nose of the aircraft to rise. As the nose rises the angle of the wings also increases and create lift by 'air deflection' and 'bernoullis principle'. Many other factors are involved to create lift, these are just the main principles.


What is basic principle of keeping an airplane afloat in air?

The basic principle is keeping it moving forward fast enough for the wings to get 'lift'. That is of course a simplification as there is much more to it


How much do the wings of an airplane weigh?

Airplane? What airplane? My paper airplane wings weigh less than 8 grams.


What is the importance of wings on an airplane?

The importance of wings is critical to an airplane, they produce lift that can sustain the airplane in the air.


How is an airplane able to stay in the air even though the airplane is heavier than the air?

While the airplane moves, the air pushes up against the wings. This has to do with the special shape of the wing, and, to a great part, to Bernoulli's principle.


What is the bernoullis principle in flying?

The Bernoulli's principle states that as the speed of a fluid (such as air) increases, its pressure decreases. In flying, this principle is applied to the wings of an aircraft, where the shape and angle of the wing cause air to move faster over the top surface than the bottom surface. This speed difference creates lower pressure above the wing, resulting in lift.
