Question 1.
Define average velocity in fluid mechanics.
Show hintHide hint
Think about how it relates to the distance traveled and time taken.
Question 2.
What are major losses in pipe flow?
Show hintHide hint
Consider where the primary resistance in pipe flow comes from.
3Question 3.
What is a velocity defect?
- The speed at which fluid flows.
- Deviation of the actual velocity from average velocity.
- The total mechanical energy loss.
Show hintHide hint
Relate it to how 'defective' flows compare to the mean scenario.
4Question 4.
True or False: Major losses are caused only by fittings.
- True
- False
Show hintHide hint
Consider the primary source of resistance in pipe flow.
Question 5.
Given a piping system with three pipes in series, each with a defined friction factor and lengths, determine the total head loss and the final flow rate at the outlet.
Show hintHide hint
Adjust for both major and minor losses from each segment.
Question 6.
You have a junction with three tanks feeding into one output pipe; if one tank is emptying faster than the others, how does this affect the outgoing flow rate?
Show hintHide hint
Think about how the total input equates to the output!
