Fluid Fundamentals
A substance, liquid or gas, that flows and takes the shape of its container.
The measure of a fluid's resistance to flow, also known as a fluid's internal friction or "thickness".
What is viscosity?
The formula for this measurement is mass divided by volume.
What is density?
The formula for pressure is force divided by this specific term.
What is area?
Technology that uses pressurized liquid to transfer energy and create motion.
What is hydraulics?
A theory stating that all physical things are made of these constantly moving units.
What is the Particle Theory of Matter?
Increasing this factor typically reduces a fluid's viscosity.
What is temperature?
The upward force a fluid applies on an object placed in it.
What is buoyant force?
To increase pressure using the same force, you must do this to the surface area.
You must decrease it.
Technology that uses compressed gas to create mechanical motion.
What is pneumatics?
The amount of space an object or substance occupies.
What is volume?
These physical barriers, like valves or bends, cause turbulence and slow flow in tubes or pipes for fluids.
This will count for double the amount of points if answered correctly.
What are obstructions?
Objects will float if they are less dense than the fluid, or if the fluid possesses a buoyant force that is ____ to the object's weight.
Greater.
If the volume of a container is reduced, this happens to the internal pressure.
It increases.
This biological organ functions as a natural hydraulic dual-pump system.
What is the heart?
A substance that is rigid, does not flow, and keeps its own shape.
What is a non-fluid?
This factor describes the resistance created between a fluid and the walls of a tube.
What is friction?
The state of matter that generally has the lowest density.
What is gas?
These wide vehicle parts are designed to increase surface area and reduce pressure on the ground on farms.
This will count for double the amount of points if guessed correctly.
What are tractor tires?
Unlike air, water is described by this term because its volume does not change under pressure.
What is incompressible?
The measure of the force of gravity pulling on an object.
What is weight?
A substance with a high viscosity of 100 000.
This will count for double the amount of points if answered correctly.
What is tar?
This occurs when an object stays in the middle of a fluid because its density is equal to the fluid's density.
What is suspension?
According to particle theory, pressure is caused by particles doing this to the walls of a container.
What is colliding?
These biological organs function as a pneumatic system by changing internal pressure to move air.
What are the lungs?
