Interactive Quizzes
Engage in quick quizzes to reinforce what you've learned and check your comprehension.
Question 1
What is the formula for calculating head loss at an entrance?
- h_L = K_{entrance} * V^2 / 2g
- h_L = V^2 / 2K_{entrance}g
- h_L = K_{entrance} * 2g / V^2
💡 Hint: Remember the context of head loss in hydraulic systems.
Question 2
True or False: A sharper pipe entrance generally results in less head loss.
- True
- False
💡 Hint: Think about how different shapes impact fluid flow.

Challenge Problems
Push your limits with challenges.
Question 1
A pipe with a sharp-edged entrance has a diameter of 0.2 meters and an incoming velocity of 2 m/s. Calculate the head loss.
💡 Hint: Apply the head loss formula and substitute the given values.
Question 2
If a well-rounded pipe entrance also has a velocity of 3 m/s and K entrance = 0.04, what is the head loss?
💡 Hint: Use the head loss formula and ensure you are using the correct K entrance for rounding.
