Question 1.
What is the no slip boundary condition?
Show hintHide hint
Consider what happens at a stationary surface.
Question 2.
What is a boundary layer?
Show hintHide hint
Think about how fluid velocity behaves near surfaces.
3Question 3.
What is the no slip boundary condition?
- The velocity is constant across the flow
- Fluid velocity at the boundary equals boundary velocity
- Fluid does not stick to the surface
Show hintHide hint
Think about how fluid interacts with surfaces.
4Question 4.
True or False: The boundary layer is a region where the fluid velocity is constant.
- True
- False
Show hintHide hint
Remember how velocity behaves near surfaces.
Question 5.
You have a fluid flowing over a flat plate with a free-stream velocity of 10 m/s and dynamic viscosity of 0.001 Pa·s. Calculate the boundary layer thickness at a distance of 1m from the leading edge.
Show hintHide hint
Consider how to use the Reynolds number to find the thickness.
Question 6.
Explain how increasing the fluid temperature might affect the boundary layer thickness and transition point of the flow from laminar to turbulent.
Show hintHide hint
Think about the effects of temperature on viscosity and fluid behavior.
