Interactive Quizzes
Engage in quick quizzes to reinforce what you've learned and check your comprehension.
Question 1
What is the equation for average velocity in smooth pipes?
- u - V_average = 5.75 log_10(y/R) + 3.75
- V_average = 5.75u + 3.75y
- u = V_average * R
💡 Hint: Recall the derivation we did in class!
Question 2
True or False: The average velocity in rough pipes differs from smooth pipes.
- True
- False
💡 Hint: Think about the generalization of the equations.
