Particle Theory
What are the 6 points of the particle theory?
What is a hydraulic system?
What is a pneumatic system?
hydraulic- A system that uses a liquid under pressure to preform a task
pneumatic- A system that uses a gas under pressure to preform a task
What happens to an object when its density is lighter than the fluid surrounding it?
it floats
this is measured by comparing distance to time...
flow rate
A fluid is anything that...
flows
What is Pascal's law?
the force applied to a fluid is distributed equally throughout all parts of the fluid
Why is there less air pressure the greater the altitude?
the air becomes less dense as there are fewer layers of air and there are fewer particles
What are 2 of the 4 factors that affect a fluids flow rate?
- the amount of force exerted on the fluid
- the type of fluid that's flowing
- the size of the opening the fluid is flowing out of
- the type of surface the fluid is flowing over
A fluids flow rate is based on how strong the...
particles attract to one another
What is Archimedes' principle?
an object immersed in a fluid experiences a buoyant force that is equal to the weight of the fluid displaced
A gas becomes more viscous when______ is applied. why?
heat because the particles gain so much energy it creates friction as they rub against each other
This is the #1 factor that affects a fluids flow rate...
temperature
This is the study of the behaviour of fluids both in motion and resting...
fluid mechanics
The upward force in a fluid is called...
buoyant force
All matter is made up of...
particles
What is flow rate?
the speed at which a fluid moves in a certain amount of time
True or Flase: A force applied to a contained fluid is transferred throughout a fluid equally and in the opposite direction from where it is applied.
