DC -- Continuity principle

The amount of fluid that moves past a given point per unit of time.

• flow rate

• fluid volume

• fluid motion

• fluid continuity

What variables are used to calculate the flow rate?

• density and volume of the fluid

• area of the fluid and volume of the tube

• diameter of the tube and volume of the fluid

• area of the tube and velocity of the fluid

What property of the hose changed?

• the volume of the fluid

• the flow rate

• the diameter of the hose

• the density of the fluid

What happens to the flow rate when the area of the hose opening changes?

• Increases

• Decreases

• Remains the same

In order for the flow rate to remain unchanged, what must happen?

• The area of the hose must increase.

• The velocity of the fluid must increase.

• The volume of the fluid must increase.

• The flow rate increases.

Why does the velocity of the fluid increase at v₂ ?

Select all correct answers.

• The area of the tube opening has decreased.

• The area of the tube opening is larger.

• There is no other place for the fluid to go.

• The fluid is not compressible.

• The fluid volume decreases.

The amount of fluid that goes in one end of a tube in any specified amount of time is equal to the amount that comes out the other end in the same amount of time.

• the Bernoulli principle

• the Conversion principle

• the Continuity principle

• the Flow Rate principle

In order for the mass of fluid at Position 1 to equal the mass of fluid at Position 2, what must be true?

• The density of the fluid must decrease.

• The volume of fluid must increase.

• The diameter of Position 2 must remain unchanged.

• The velocity of the fluid must increase.
