Hydraulics Quiz

How does liquid in a hydraulic system behave?

• Like a gas

• Like a solid

• Like a plasma

• Like a vacuum

Why does liquid in a hydraulic system behave like a solid?

• Because it compresses a lot

• Because it compresses very little

• Because it expands rapidly

• Because it evaporates quickly

What does Pascal's Law state about the pressure exerted by a confined fluid?

• It acts undiminished equally in all directions.

• It decreases with depth.

• It increases with temperature.

• It acts only in the direction of gravity.

What is the definition of Flow Rate?

• The distance the fluid travels through a system in a given period of time

• The volume of fluid that moves through a system in a given period of time

• The speed at which fluid moves through a system

• The pressure exerted by the fluid in a system

What is the definition of Flow Velocity?

• The volume of fluid that moves through a system in a given period of time

• The speed at which fluid moves through a system

• The distance the fluid travels through a system in a given period of time

• The pressure exerted by the fluid in a system

What is the symbol for Flow Rate?

• V

• A

• Q

• F

What is the example unit for Flow Velocity?

• gpm or gal/min

• in.³ / min

• in.²

• fps or ft/s

What is the formula for Flow Rate (Q)?

• Q = V / A

• Q = V * A

• Q = A / V

• Q = V + A

What is the conversion factor from gallons to cubic inches?

• 1 gal = 100 in.³

• 1 gal = 200 in.³

• 1 gal = 231 in.³

• 1 gal = 300 in.³

What does Bernoulli's Principle state about the relationship between velocity and pressure?

• An increase in velocity results in an increase in pressure.

• An increase in velocity results in a decrease in pressure.

• A decrease in velocity results in a decrease in pressure.

• Velocity and pressure are not related.
