Interactive Quizzes
Engage in quick quizzes to reinforce what you've learned and check your comprehension.
Question 1
What is the primary formula for calculating head loss during gradual enlargement?
- hL = KE(V1^2 - V2^2)/(2g)
- hL = V1^2/(2g)
- hL = V2^2/(2g)
💡 Hint: Consider how different velocities impact the pressure in the system.
Question 2
True or False: K_E is generally higher for sudden enlargements than gradual enlargements.
- True
- False
💡 Hint: Reflect on how turbulence relates to energy loss.

Challenge Problems
Push your limits with challenges.
Question 1
A piping system is designed to transport water through several stages of enlargement. Calculate the head loss if the fluid velocities in the smaller and larger sections are 5 m/s and 2 m/s respectively. Use K_E = 0.85.
💡 Hint: Be sure to work through the steps of the formula carefully!
Question 2
In a hydraulic project, the designer must choose between sudden and gradual expansions. What factors should influence this choice, and how might you mathematically justify using gradual expansions?
💡 Hint: Reflect on the overall system efficiency and how each method impacts performance.
