Question 1.
Define the term 'boundary layer thickness'.
Show hintHide hint
Think about how 'thickness' relates to layers of flow.
Question 2.
What is the distinction between laminar and turbulent flow?
Show hintHide hint
Consider the flow characteristics.
3Question 3.
What is the transition zone?
- A smooth flowing region
- The area where flow changes from laminar to turbulent
- Where flow is always turbulent
Show hintHide hint
Remember the transformation of flow types.
4Question 4.
True or False: In a laminar sub-layer, the velocity profile is constant.
- True
- False
Show hintHide hint
Consider how velocity changes in this layer.
Question 5.
Evaluate how doubling the speed of a flat plate would influence the boundary layer thickness.
Show hintHide hint
Think about the relationship between speed, Reynolds number, and flow behavior.
Question 6.
Derive the formula for displacement thickness in a practical scenario involving a pipe flow.
Show hintHide hint
Look into fluid dynamic principles that relate area and velocity changes.
