Fluid stat Concepts

International unit (SI) of density is,

• g ml⁻¹

• g cm^-3

• kg m^-3

• kg cm^-3

Consider the following statements on the density of a liquid

A. Density of a liquid depends on its mass.

B. Density of a liquid depends on its volume.

C. Density of a liquid depends on the kind of liquid.

• Only A

• Only B

• Only C

• Only A and B

• Only B and C

When a fluid fills a closed container, it exerts pressure

• only on the bottom of the container

• only on the sides of the container

• only on particles within the fluid

• everywhere inside the container

The pressure of water exerted on the fishes is P_X, P_Y and P_Z respectively.
Which comparison is correct about the pressure exerted on the fishes?

• P_Z > P_Y > P_X 
• P_Z = P_X < P_Y
• P_Z = P_X > P_Y
• P_Z < P_X < P_Y

Where is pressure the greatest on the dam?

• D
• C
• B
• A

The upward force exerted by a fluid is called the...

• buoyancy force

• density force

• fluidity force

• normal force

Fluid pressure is directed

• in all directions.
• only upward.
• only downward.
• always sideways.

When pressure is applied to a confined fluid, the increase in pressure is transmitted equally to all parts of the fluid. This fact is called________.

• Pascal's Principle
• Newton's Principle
• Archimedes' Principle
• Bernoulli's Principle
