Question 1
What is the primary function of a hydrodynamic boundary layer?
- To increase velocity from zero to free stream
- To decrease temperature of the fluid
- To provide resistance against flow
💡 Hint: Focus on the flow characteristics near surfaces.
Question 2
True or False: A higher Prandtl number means a thicker thermal boundary layer.
- True
- False
💡 Hint: Think about what Prandtl number relates to.

Challenge Problems
Push your limits with challenges.
Question 1
In a flow configuration where air flows over a heated surface, how would you analyze the effects of increasing surface length on boundary layer development?
💡 Hint: Consider how the boundary layer thickness influences flow dynamics.
Question 2
Consider a vertical plate in natural convection. If the surface temperature is increased significantly, what happens to the thermal boundary layer and heat transfer rates?
💡 Hint: Think about the effect of density changes with temperature in the fluid flow.
