What is Hydraulics?
200
A measure of the speed at which a fluid flows from one point to another.
What is flow rate?
200
Describes how closely packed together the particles are in a substance.
What is Density?
200
The tendency of an object in a fluid to rise or sink due to density differences with its surroundings.
What is buoyancy?
200
The amount of force applied to a given area.
What is pressure?
200
Devices that transmit applied forces through gases to move something else.

300
The resistance of a fluid to flow
What is viscosity?
300
State of matter that has the least density.
