Ch. 4 Fluid Systems

What is a hydraulic system?

• A system that uses a liquid under pressure to transmit a force to do work.

• A system that uses a gas under pressure to transmit a force to do work

• Pascal's law.

• It uses water to push an object.

What does Pascal's law state?

• When you apply a small amount of pressure to a compressed fluid, it will send that pressure nowhere.

• When you apply pressure to a confined fluid, the fluid will send that pressure out in all directions at the same rate.

• When you apply a large amount of pressure to an object, it will float.

• When you use a fluid to apply pressure, the pressure will release.

IF we are using Boyles' law and our Pressure goes UP, what must our volume do?

• Increase

• Decrease

• Stay the same

Which one is an example of a pneumatic system?

• 
• 
• 
• 

What is a pump?

• A fluid system that allows pressure to be applied to another object.

• Compressed air that pushes out pressure from an object.

• A mechanical device or part that is used to move a fluid through or into something.

• A mechanical device that does not move a fluid.

What is a valve?

• A mechanical device or part that moves a fluid through or into something.

• A system that allows a fluid to move quickly.

• A mechanical fluid system that releases pressure.

• A mechanical device or part that controls the flow of fluids.

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.

A hydraulic system includes all of the following except:

• Compressor

• Reservoir

• Fluid

• Pump

• Valves

___________ systems have active components such as a gas compressor, transition lines, air tanks, hoses, open atmosphere, and passive components.

• Pneumatype

• Hydraulic

• Pneumatic

• Hydrophobic

___________ pressure equals total pressure minus atmospheric pressure.

• Absolute
• Fluid
• Gage
• Vapor
