What is the Bernoulli principle?

• The Bernoulli principle states that as the speed of a fluid decreases, its pressure increases.

• The Bernoulli principle states that as the speed of a fluid increases, its pressure increases.

• The Bernoulli principle states that as the speed of a fluid increases, its temperature decreases.

• The Bernoulli principle states that as the speed of a fluid increases, its pressure decreases.

What is Archimedes' principle?

• Archimedes' principle states that when a body is partially or fully submerged in a fluid, it experiences a sideways buoyant force.

• Archimedes' principle states that when a body is partially or fully submerged in a fluid, it experiences no buoyant force.

• Archimedes' principle states that when a body is partially or fully submerged in a fluid, it experiences a downward buoyant force equal to the weight of the fluid displaced by the body.

• Archimedes' principle states that when a body is partially or fully submerged in a fluid, it experiences an upward buoyant force equal to the weight of the fluid displaced by the body.

State the law of flotation based on Archimedes' principle.

• A body floats in a fluid if the weight of the fluid displaced by the body is less than the weight of the body.

• A body floats in a fluid if the weight of the fluid displaced by the body is greater than the weight of the body.

• A body floats in a fluid if the weight of the fluid displaced by the body is unrelated to the weight of the body.

• A body floats in a fluid if the weight of the fluid displaced by the body is equal to the weight of the body.

Explain how Bernoulli's principle is applied in a Venturi meter.

• The pressure difference in a Venturi meter is caused by the temperature difference.

• Bernoulli's principle is not applied in a Venturi meter.

• The principle of conservation of energy is used to measure the flow rate of fluid in a Venturi meter.

• The flow rate of fluid in a Venturi meter is measured using the principle of gravity.

What is the equation for Bernoulli's principle?

• P + 1/2 * ρ * v^2 + ρ * g * h = constant

• P + 1/2 * ρ * v^2 + ρ * g * h = 0

• P + 1/2 * ρ * v^2 - ρ * g * h = constant

• P + 1/2 * ρ * v^2 + ρ * g * h = variable

How does Bernoulli's principle explain the lift generated by an airplane wing?

• Bernoulli's principle explains that the lift generated by an airplane wing is caused by the weight of the airplane.

• Bernoulli's principle explains that the difference in air pressure created by the shape of an airplane wing generates lift.

• Bernoulli's principle explains that the lift generated by an airplane wing is a result of the engine power.

• Bernoulli's principle explains that the lift generated by an airplane wing is due to the rotation of the wing.

What is the Coanda effect and how is it related to Bernoulli's principle?

• The Coanda effect is the tendency of a fluid jet to split into multiple smaller jets when it encounters a nearby surface. It is related to Bernoulli's principle as the fluid flow near the surface creates a pressure difference, causing the jet to break apart.

• The Coanda effect is the tendency of a fluid jet to repel a nearby surface and move away from it. It is related to Bernoulli's principle as the fluid flow near the surface creates a pressure difference, causing the jet to be deflected away from the surface.

• The Coanda effect is the tendency of a fluid jet to be attracted to a nearby surface and follow its contour. It is related to Bernoulli's principle as the fluid flow near the surface creates a pressure difference, causing the jet to be deflected towards the surface.

• The Coanda effect is the tendency of a fluid jet to remain stationary when it encounters a nearby surface. It is related to Bernoulli's principle as the fluid flow near the surface creates a pressure difference, causing the jet to stay in place.

Explain the working of a carburetor based on Bernoulli's principle.

• A carburetor works by using a vacuum to draw fuel into the engine.

• A carburetor works by compressing fuel to create a low-pressure area.

• A carburetor works by using electricity to draw fuel into the engine.

• A carburetor works by creating a low-pressure area using Bernoulli's principle to draw fuel into the engine.
