Consider how viscosity affects momentum.
3Question 3.
What is momentum thickness?
- The thickness of the boundary layer
- The loss of momentum flux compared to potential flow
- The velocity at the surface

4Question 4.
True or False: Displacement thickness affects the shape of an object in a fluid.
- True
- False
Show hintHide hint
Reflect on how streamline displacement affects drag.
Question 5.
A fluid with a non-uniform velocity profile flows over a flat plate. Calculate the displacement, momentum, and energy thickness given the profile: u / U = 3y/delta - y^2/delta^2, where delta is the boundary layer thickness.
