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.
Because of their properties, fluids are extremely useful as parts of systems that perform work.
True.
False.
Unsure.
None of the above.
Which one is a "natural" fluid system?
Vaccum cleaner.
Heating and cooling systems.
Sea star.
Car hoist.
Which one is an example of a manufactured fluid system?
Water cycle.
Root system in plants.
Respiratory system.
Sewer system.
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.
A hoist uses hydraulic pressure to lift a car.
True.
False.
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.
Which one is an example of valves?
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.
How are a hydraulic system and a pneumatic system similar?
Both use a gas.
Both use water.
Both use a fluid to apply force.
Both use valves and pistons.
What parts of fluid systems are also found in the human body?
Valves.
Compressible and incompressible fluids.
Pumps.
Pistons.
which one is an example of Pascal's law?
A bathtub overflows with water when you leave the faucet running too long.
Toothpaste moves throughout the tube when you squeeze it with the cap still on.
Warm are from a hair dryer blows through your hair.
