The relationship between the velocity and pressure exerted by a moving liquid is described by the Bernoulli's principle: as the velocity of a fluid increases, the pressure exerted by that fluid decreases.
Airplanes get a part of their lift by taking advantage of Bernoulli's principle. Race cars employ Bernoulli's principle to keep their rear wheels on the ground while traveling at high speeds.
Bernoulli's principle, physical principle formulated by Daniel Bernoulli that states that as the speed of a moving fluid (liquid or gas) increases, the pressure within the fluid decreases. The phenomenon described by Bernoulli's principle has many practical applications; it is employed in the carburetor and the atomizer, in which air is the moving fluid, and in the aspirator, in which water is the moving fluid. In the first two devices air moving through a tube passes through a constriction, which causes an increase in speed and a corresponding reduction in pressure. As a result, liquid is forced up into the air stream (through a narrow tube that leads from the body of the liquid to the constriction) by the greater atmospheric pressure on the surface of the liquid. In the aspirator air is drawn into a stream of water as the water flows through a constriction. Bernoulli's principle can be explained in terms of the law of conservation of energy (see conservation laws, in physics). As a fluid moves from a wider pipe into a narrower pipe or a constriction, a corresponding volume must move a greater distance forward in the narrower pipe and thus have a greater speed. At the same time, the work done by corresponding volumes in the wider and narrower pipes will be expressed by the product of the pressure and the volume. Since the speed is greater in the narrower pipe, the kinetic energy of that volume is greater. Then, by the law of conservation of energy, this increase in kinetic energy must be balanced by a decrease in the pressure-volume product, or, since the volumes are equal, by a decrease in pressure.

Bernoullis principle what characteristic of a moving fluid determines its pressure?
The speed of the fluid is what determines its pressure in relation to Bernoulli's principle. As the speed of the fluid increases, the pressure decreases according to the principle.
What does bernoullis principle say about the speed of a moving fluid?
Bernoulli's principle states that as the speed of a fluid increases, its pressure decreases, and vice versa. This means that in a moving fluid, areas with higher speed will experience lower pressure compared to areas with lower speed.
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 is the rule that states that as the speed of a moving fluid increases the pressure within the fluid decreases?
This rule is known as Bernoulli's principle. It states that as the speed of a fluid increases, the pressure within the fluid decreases, and vice versa. This principle is commonly used in fluid dynamics to explain phenomena such as lift on an airplane wing or the flow of water through a pipe.
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.
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.
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.

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.
