Interactive Quizzes
Engage in quick quizzes to reinforce what you've learned and check your comprehension.
Question 1
What formula is used to calculate head loss in sudden enlargement?
- h_L = K_E * (V_1^2)/(2g)
- h_L = K_L * (V_1^2)/(2g)
- h_L = K_B * (V_1^2)/(2g)
💡 Hint: Recall the type of enlargement being discussed.
Question 2
True or False: The head loss coefficient K_exit is generally 0.
- True
- False
💡 Hint: Think about the implications of what happens at a pipe exit.

Challenge Problems
Push your limits with challenges.
Question 1
A water system has a sudden enlargement from 5 cm to 15 cm, and water flows at 4 m/s in the smaller pipe. Calculate the head loss using appropriate coefficients.
💡 Hint: Focus on proper area calculations.
Question 2
For a steady pipe system with a gradual expansion leading to reduced head losses, calculate the head loss if the initial velocity is 5 m/s and you have K_E = 0.8.
💡 Hint: Pay attention to velocity changes between points!
