in a steady flow, the sum of all forms of mechanical energy in a fluid along a streamline is the same at all points on that streamline. if the air flowing past the top surface of a wing is moving faster than the air flowing past the bottom surface, then Bernoulli's principle implies that the pressure on the surfaces of the wing will be lower above than below. thus allowing the pressure below to push up on the wing, thus generating lift.

Bernoullis principle about air velocity and pressure?
velocity and pressure have inverse relation. when velocity increases then pressure at that point decrease and vice versa.
How does air act like a fluid as it has speed?
because it flows from cold to warm areas and around solid objects. Which is what bernoullis principle is based on. the basis of flight..
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.
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
How does bernoulli's principle keep airplanes in the air?
Bernoulli's principle is that there is a region of high pressure under the wing. So air rushes under the plane. So it creates lift which in turn keeps the airplane in the air.
How does hydrogen keep an airship afloat?
Hydrogen is lighter than air, making it buoyant, because air is a fluid. It works on the same principle as floating wood.
What support a bird to fly?
The difference between the air pressure on the underside of it's wings, and the air pressure on the top side of it's wings. It is called "lift" - and is the basic principle of flight of any kind.
Why do down feathers keep a bird warm?
Feathers are efficient structures for trapping air. Motionless air is a very good thermal insulator.
How do you you make a bird on alxemy?
Air+Lizard= Bird
Explain how bernoulli's principle can keep a bird in the air?
Bernoulli's principle states that as the speed of a fluid increases, its pressure decreases and vice versa. The wing of a bird is designed the same way as the wing of an airplane. The air flowing over the top of the wing must travel a further distance in the same time that the air under the wing travels a shorter distance. Since the airflow over top has to go further in a shorter time, it must travel at a higher velocity, thereby creating a region of lower pressure on top of the wing. With a high pressure region under the wing and a low pressure region above the wing, the net force is upwards and is known as "lift". Assuming that the force of lift is equal to or greater than the force of gravity, then the bird will remain in the air.
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.
