Question 1.
Define mass conservation.
Show hintHide hint
Think about the law of conservation in physics.
Question 2.
What is a control volume?
Show hintHide hint
Consider the volume through which fluid flows.
3Question 3.
What does the mass conservation equation express?
- Rate of mass inflow
- Rate of mass outflow
- Rate of change of mass storage
Show hintHide hint
Think about how mass interacts in a closed system.
4Question 4.
True or False: In incompressible flow, changes in density can occur.
- True
- False
Show hintHide hint
Consider what incompressible means.
Question 5.
A control volume of fluid experiences inflow at a rate of 5 kg/s and outflow at 3 kg/s. If the initial mass in the control volume is 10 kg, what is the new mass after 5 seconds?
Show hintHide hint
Identify inflow and outflow rates correctly before calculating.
Question 6.
Explain how changes in pressure affect compressible fluid flow and derive a modified mass conservation equation considering variable density.
Show hintHide hint
Recall how the ideal gas law connects pressure and density.
