Show hintHide hint
Think about how we analyze fluid properties.
Question 2.
Define mass conservation.
Show hintHide hint
Consider inflow and outflow in your answer.
3Question 3.
What is the differential approach in fluid mechanics?
- Analyzing the bulk flow of fluid
- Studying fluid at individual points
- Understanding control volumes
Show hintHide hint
Think about the focus of the analysis.
4Question 4.
True or False: The integral approach provides detailed information about the velocity and pressure fields inside a control volume.
- True
- False
Show hintHide hint
Remember the concept of the black box.
Question 5.
Consider a fluid flowing through a pipe with varying diameter. Using the differential approach, derive the continuity equation and explain each step.
Show hintHide hint
Use concepts from mass conservation and think about how area changes affect flow.
Question 6.
Using the divergence theorem, calculate the mass flow rate through a surface integrally from a given velocity field.
Show hintHide hint
Relate the volumetric flow to the surface area and velocity vectors involved.
