Interactive Quizzes
Engage in quick quizzes to reinforce what you've learned and check your comprehension.
Question 1
What is the equation for the power law velocity profile in smooth pipes?
- u = u_max (1 - r/R)^(1/7)
- u/u_max = (y/R)^(1/n)
- u = 5.75 log(y/R)
💡 Hint: Recall how we express velocity profile for laminar and turbulent cases.
Question 2
True or False: The average velocity is the same for smooth and rough pipes.
- True
- False
💡 Hint: Consider the observations we made during discussion.

Challenge Problems
Push your limits with challenges.
Question 1
Given a power law velocity profile u(r) = u_max (1 - r/R)^(1/5), calculate the average velocity in terms of u_max.
💡 Hint: Look closely at the integration limits and how to apply the formula!
Question 2
For a specific Reynolds number, if the power law exponent n increases from 5 to 10, assess how this affects the velocity gradient near the walls.
💡 Hint: Consider the relationship between n and flow turbulence.
