Question 1.
What is the transition zone?
Show hintHide hint
Think about where flow order changes.
Question 2.
Define laminar sub-layer.
Show hintHide hint
Consider its proximity to the solid surface.
3Question 3.
What happens in the transition zone?
- A) Viscosity decreases
- B) Flow becomes laminar
- C) Flow transitions to turbulent
Show hintHide hint
Consider the flow dynamics.
4Question 4.
True or False: The velocity profile inside the laminar sub-layer is assumed to be linear.
- True
- False
Show hintHide hint
Think about viscous effects.
Question 5.
A fluid with a Reynolds number of 4000 flows past a flat plate. Describe what happens as this fluid continues flowing downstream.
Show hintHide hint
Consider flow stability and flow rates.
Question 6.
Calculate the boundary layer thickness (δ) at a specific point using the 99% free stream velocity approximation, given the properties of the fluid and flow conditions.
Show hintHide hint
Refer to boundary layer theory and relevant equations.
