Question 1.
Define boundary layer thickness.
Show hintHide hint
Check the relation between the surface and free stream velocity.
Question 2.
What is the purpose of the Reynolds number in fluid dynamics?
Show hintHide hint
Think about how fluid behavior changes at different flow conditions.
3Question 3.
What parameter does the Reynolds number help determine?
- Whether flow is laminar or turbulent
- Shear stress amount
- Frictional losses
Show hintHide hint
Consider how fluid flows differently under various conditions.
4Question 4.
True or False: Boundary layer thickness decreases with increasing flow speed.
- True
- False
Show hintHide hint
Reflect on how flow dynamics work with varied velocities.
Question 5.
Given a viscosity of 0.001 N.s/m^2, find the boundary layer thickness after 2 m if fluid velocity is 0.5 m/s.
Show hintHide hint
Remember that \\(Re = \\frac{\\rho U x}{\\mu}\\) may require you to know the density of the fluid.
Question 6.
Explain how the assumption of laminar flow affects the results of your calculations regarding the boundary layer.
Show hintHide hint
Consider how fluid dynamics differs in turbulent conditions.
