Interactive Quizzes
Engage in quick quizzes to reinforce what you've learned and check your comprehension.
Question 1
What is the hydrolic diameter formula?
- D_h = A/P
- D_h = 4(A/P)
- D_h = P/4A
💡 Hint: Recall how we calculate equivalent diameters.
Question 2
Wall shear stress varies in laminar flow.
- True
- False
💡 Hint: Think about how flow conditions affect stress distribution.

Challenge Problems
Push your limits with challenges.
Question 1
You are tasked to design a non-circular conduit for a city water supply. How would you approach the determination of hydraulic diameter and wall shear stress?
💡 Hint: Consider if the pipe will operate in laminar or turbulent conditions.
Question 2
A flow in a triangular pipe exhibits a non-uniform velocity profile. Explain how you would determine the wall shear stress for this scenario.
💡 Hint: Relate back to the discussion on laminar vs turbulent flow.
