2A.3 Visocity Flashcards
1
Q
the frictional force in fluids is due to
A
viscosity
2
Q
if the viscosity is low
A
then the frictional force caused by movement in the fluid is small
3
Q
what is viscosity
A
how resistant is to flowing
4
Q
what is the coefficient of velocity
A
it is a numerical value given to a fluid to indicate how much it resists flow
5
Q
viscosity is inversely proportional to the
A
rate of flow of a fluid in a pipe
6
Q
what does viscosity determine
A
- frictional force in the fluid
2. the rate of flow of a fluid
7
Q
as the temperature of the fluid increases in gases the viscosity
A
increases
8
Q
as the temperature of the fluid increases in liquids the viscosity
A
decreases
