Question 1.
What happens to fluid velocity at a stationary wall?
Show hintHide hint
Consider the effect of sticking on the boundary.
Question 2.
What is a boundary layer?
Show hintHide hint
Think about fluid motion near solid boundaries.
3Question 3.
What is the velocity at the boundary of a stationary wall?
- Free Stream Velocity
- Zero
- Half of Free Stream Velocity
Show hintHide hint
Recall the behavior of fluid at surfaces.
4Question 4.
True or False: The boundary layer grows thicker as you move downstream.
- True
- False
Show hintHide hint
Consider how flow develops over time.
Question 5.
A flat plate in a fluid stream experiences a transition from laminar to turbulent flow. Analyze the implications for drag force if the Reynolds number increases significantly.
Show hintHide hint
Consider how flow dynamics change with turbulence.
Question 6.
Calculate the boundary layer thickness delta at x = 2 m, given a free stream velocity U of 10 m/s and kinematic viscosity nu of 1 x 10^-6 m²/s.
Show hintHide hint
Use the relation provided for calculating delta based on free stream velocity and viscosity.
