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 sudden enlargement?
- h_L = K_L * (V_1^2 / 2g)
- h_L = K_E' * (V_1^2 - V_2^2) / 2g
- h_L = K_b * (V^2 / 2g)
💡 Hint: Focus on the coefficient that corresponds to sudden changes.
Question 2
True or False: The exit loss coefficient is always less than the entrance loss coefficient.
- True
- False
💡 Hint: Consider how fluid exits a pipe compared to entering.

Question 1
A 10 m long pipe transitions from a diameter of 0.1 m to 0.3 m abruptly. Calculate the head loss if the flow velocity is 5 m/s.
💡 Hint: Remember to calculate the areas before applying the head loss formula.
Question 2
Design a water supply system with a series of pipes including one abrupt enlargement and two sharp bends. Estimate total head loss using given coefficients.
💡 Hint: Break down the system into manageable sections and tackle each separately.
