Fluids Flashcards
1
Q
Density
A
the mass per unit volume for a given material
2
Q
fluids
A
objects that can flow, these include liquids and gases
3
Q
streamlines
A
the path taken by small regions of fluids
4
Q
laminar flow
A
where streamlines do not pass over one another
5
Q
turbulent flow
A
where streamlines cross, leading the formation of vortices and eddy currents
6
Q
viscosity
A
a quantity that describes a fluids resistance to flow
7
Q
newtonian fluid
A
- fluids where viscosity is constant for a given temperature
8
Q
non newtonian fluids
A
- fluids where viscosity is not constant for a given temperature
9
Q
pressure
A
a measure of how much force is acting against an area
10
Q
bernoulli’s principle
A
at points along a horizontal streamline, higher pressure regions have lower fluid speed and lower pressure regions have higher fluid speed
