Question 1.
What is head loss in a hydraulic system?
Show hintHide hint
Consider the relationship between energy and fluid motion.
Question 2.
What is the formula for head loss due to gradual enlargement?
Show hintHide hint
Think about the factors influencing fluid velocity.
3Question 3.
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)
Show hintHide hint
Consider how different velocities impact the pressure in the system.
4Question 4.
True or False: K_E is generally higher for sudden enlargements than gradual enlargements.
- True
- False
Show hintHide hint
Reflect on how turbulence relates to energy loss.
Question 5.
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.

Be sure to work through the steps of the formula carefully!
Question 6.
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?
Show hintHide hint
Reflect on the overall system efficiency and how each method impacts performance.
