Question 1.
Define energy loss in the context of fluid flow.
Show hintHide hint
Think about how fluid interacts with surfaces.
Question 2.
What is the purpose of a valve in a fluid system?
Show hintHide hint
Consider how traffic lights work.
3Question 3.
What happens when a valve is partially closed?
- Flow increases
- Flow remains the same
- Flow decreases
Show hintHide hint
Think about how closing a tap reduces water flow.
4Question 4.
True or False: Energy loss is constant in laminar flow.
- True
- False
Show hintHide hint
Consider how smooth vs. rough surfaces affect flow.
Question 5.
A fluid flows through a pipe with a sudden diameter reduction. Calculate the expected increase in velocity and energy loss using Bernoulli’s principle and illustrate with a sketch.
Show hintHide hint
Remember to take into account the initial and final pressures.
Question 6.
If a system incorporates both a globe valve and a gate valve, how would you calculate the total energy losses and flow rates? Provide a comprehensive analysis.
Show hintHide hint
Use the K values associated with each valve type for accurate calculations.
