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?
Bernoulli's principle states that as the velocity of a fluid (such as air) increases, its pressure decreases, and vice versa. This means that if air is moving faster, the pressure exerted by that air will be lower compared to still air. This principle is important in understanding the behavior of fluids in various applications, such as in aerodynamics or fluid dynamics.
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.
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.
What uses Bernoullis principle?
Bernoulli's principle is commonly used in aviation to explain lift generation, in weather forecasting to analyze air pressure differences, and in fluid dynamics to understand the flow characteristics in pipelines and pumps.
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.
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
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 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 bernoulli's principle keep airplanes in the air?
Bernoulli's principle states that as air speed increases, air pressure decreases. This principle is applied in airplane wings, which are designed to create a pressure difference between the upper and lower surfaces. This pressure difference generates lift, allowing the airplane to stay in the air.
Why do down feathers keep a bird warm?
Feathers are efficient structures for trapping air. Motionless air is a very good thermal insulator.
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.
