Fluid Fundamentals
A substance that takes the shape of its container and can flow.
What is a Fluid?
A measure of how quickly a fluid moves from one place to another.
What is flow rate?
Smooth and orderly flow where particles move in parallel layers.
What is laminar flow?
How much mass is packed into a certain amount of space.
What is density?
The force applied over an object or certain area.
What is pressure?
All matter is made of these tiny pieces that have mass and volume.
What are particles?
A measure of how resistant a fluid is to flowing, sometimes described as thickness.
What is viscosity?
The attraction between molecules of the same type.
What is cohesion?
What happens to the density of a fluid when temperature increases.
What is density decreases?
The direction fluid moves when there are pressure differences.
What is from high pressure to low pressure?
Liquids, Gases, and ____ are all considered as fluids.
What is plasma?
When viscosity is high, the measure is low.
What is flow rate?
Type of flow that creates eddies and swirls.
What is turbulent flow?
The upward force that acts on objects in fluids.
What is buoyancy?
The reason pressure increases with depth in a fluid.
What is the weight of more fluid above?
Increasing this causes particles to move faster.
What is temperature OR kinetic energy?
Fluids flow faster when their particles have this kind of bond strength.
What are weak particle bonds?
This property causes the curved water surface (meniscus) in a graduated cylinder.
What is adhesion?
The principle stating that buoyant force equals the weight of displaced fluid.
What is Archimedes' Principle?
This fluid type is easy to compress due to widely spaced particles.
What is a gas?
The reason liquids and gases flow more easily than solids.
What are weaker particle bonds?
The type of relationship between flow rate and viscosity.
What is an inverse relationship?
This type of flow happens when a low-viscosity fluid is moving at a high flow rate, causing layers to mix due to inconsistent changes in pressure and velocity.
What is turbulent flow?
Objects float when they have this relationship to the fluid's density.
What is lower density?
The law stating that pressure applied to an enclosed fluid spreads equally throughout it.
