fluid flow

Bernoulli’s principle is defined as the___________________________________________________________.

• A. velocity in a fluid remains constant as the fluid’s pressure changes

• B. pressure in a fluid remains constant as the fluid’s velocity changes

• C. Pressure in a fluid decreases as the fluid’s velocity increases

• D. Pressure in a fluid increases as the fluid’s velocity increases

How are a hydraulic system and pneumatic system different?

• One is more powerful than the other.

• One uses a gas, and the other uses a liquid.

• One has a pump, and the other does not.

• One has more valves than the other.

What is a manometer?

• It gives answers to the exam

• It measures liquid pressure.

Shear stress in static fluid is

• always zero

• always maximum

• between zero to maximum

• unpredictable

What is the equation for pressure?

• Pressure = Force / Surface area
• Pressure = Force x Surface area
• Pressure = Force + Surface area
