Question 1.
What happens to fluid velocity as it flows through a converging nozzle?
Show hintHide hint
Think about the relationship between area and flow speed.
Question 2.
Define steady flow in your own words.
Show hintHide hint
Consider what it means for a river flowing at a constant speed.
3Question 3.
As a fluid passes through a nozzle, its velocity:
- Decreases
- Increases
- Stays constant
Show hintHide hint
Consider how squeezing a hose affects the water flow.
4Question 4.
In steady flow, time-dependent terms for acceleration are:
- True
- False
Show hintHide hint
Reflect on what 'steady' means in relation to flow parameters.
Question 5.
Design a nozzle that moves fluid from an initial velocity of 10 ft/s to an exit velocity of 30 ft/s. Discuss the class of fluid and parameters.
Show hintHide hint
Use Poiseuille's law to relate velocity to pressure drop.
