Question 1.
What is a control volume in fluid mechanics?
Show hintHide hint
It relates to what flows in and out of different boundaries.
Question 2.
Define mass flux.
Show hintHide hint
Think about how mass is distributed over an area.
3Question 3.
What does the control volume analyze in fluid mechanics?
- Only inflow
- Only outflow
- Both inflow and outflow
- None of the above
Show hintHide hint
Think about how fluid enters and exits.
4Question 4.
True or False: Mass can be created within a control volume.
- True
- False
Show hintHide hint
Consider the principles of mass conservation.
Question 5.
Consider a platform where air is being compressed in a piston. How would you model the mass conservation when density varies significantly? Illustrate with equations.
Show hintHide hint
Remember to account for the changes over time and adjust equations based on compressible flow.
Question 6.
Analyze a cylindrical control volume with varying density and velocity. How would mass conservation principles apply in this case?
Show hintHide hint
Visualize how each dimension contributes differently to mass inflow and outflow.
