Question 1.
Define laminar flow.
Show hintHide hint
Think about how fluid behaves without disruption.
Question 2.
What is viscosity?
Show hintHide hint
Consider how thick a liquid is.
3Question 3.
What happens to the velocity profile in laminar flow as the gap between plates decreases?
- Velocity increases
- Velocity decreases
- Velocity remains constant
Show hintHide hint
Think about how flow speeds up in constricted paths.
4Question 4.
True or False: Shear stress is dependent on the viscosity of the fluid.
- True
- False
Show hintHide hint
Recall the relationship between shear stress and viscosity.
Question 5.
Calculate the shear stress at the wall if the maximum velocity is 0.8 m/s and the viscosity is 0.01 Pa·s.
Show hintHide hint
Review the relationship between velocity and shear stress.
Question 6.
In a laminar flow scenario, if the distance between plates is halved, what happens to the maximum velocity?
Show hintHide hint
Consider how the geometry affects flow and apply known equations.
