Question 1.
What is the material derivative?
Show hintHide hint
Think about how fluid properties change as particles move.
Question 2.
State the conservation of mass principle.
Show hintHide hint
What happens to mass in a fluid system?
3Question 3.
What does the material derivative represent?
- Change in energy
- Change in fluid property for a moving particle
- Constant flow rate
Show hintHide hint
It focuses on the experiences of moving fluid.
4Question 4.
True or False: The continuity equation is derived from the conservation of mass.
- True
- False
Show hintHide hint
Think about what continuity means in terms of mass.
Question 5.
A fluid parcel in a pipe undergoes a pressure gradient. Analyze how this affects the mass flow rate using the continuity equation.
Show hintHide hint
Don't forget to account for changes in cross-section according to the continuity principle.
Question 6.
Devise a scenario in which the stream function is more beneficial than direct velocity analysis in predicting fluid behavior.
Show hintHide hint
Think of where visualizing pathways simplifies flow understanding.
