Question 1
What is the value of the contraction loss coefficient (k_c) for abrupt contractions?
- 0.1
- 0.5
- 0.8
💡 Hint: Think about how much turbulence is created in sudden changes.
Question 2
True or False: Gradual contractions lead to less head loss than sudden contractions.
- True
- False
💡 Hint: Consider the effects of fluid flow.

Challenge Problems
Push your limits with challenges.
Question 1
Determine the head loss in a piping system where the inlet diameter is 0.1 meters and the outlet diameter is 0.05 meters. If the flow velocity is 3 m/s, compute the loss using k_c = 0.5.
💡 Hint: Refer back to the equations used for calculations.
Question 2
In a system with varying diameters, analyze and compute head losses for both sudden and gradual transitions, comparing energy lost.
💡 Hint: Make sure to detail each step in your analysis and refer to the section for coefficients.
