Question 1
What does the average velocity represent in turbulent flow?
- Velocity at a point
- Mean velocity over a cross-section
- Velocity just at the wall
💡 Hint: Think about how averages work in general.
Question 2
True or False: The frictional velocity is irrelevant in turbulent pipe flow.
- True
- False
💡 Hint: Consider what happens when you have friction.

Challenge Problems
Push your limits with challenges.
Question 1
For a turbulent flow with a velocity profile described by u(r) = 10*(1 - (r/R))^(1/7), find the average velocity.
💡 Hint: Focus on integrating the velocity function you've been given.
Question 2
A pipe with a rough surface has a different flow profile than a smooth one. Derive how one might approach calculating average velocity for both and discuss the implications for design.
💡 Hint: Relate to common engineering practices and friction considerations.
