3 cards from this section. Quick, good the night before a test.
Define boundary layer.
Think about where flow meets a solid boundary.
What is the significance of momentum thickness?
Recall how momentum characteristics change in layers.
What does the boundary layer refer to?
Consider how viscosity interacts with surfaces in flow.
True or False: Shear stress is irrelevant in laminar flow.
Think about forces acting parallel to a surface.
Calculate the boundary layer thickness for a fluid with viscosity 0.001 N·s/m^2 flowing at 2 m/s over a 1 meter plate.
You'll need to compute the Reynolds number first!
Analyze how an increase in viscosity affects shear stress using the formula tau=mu du/dy.
Consider the effects of viscosity while keeping the gradient constant.
