Question 1.
What is the basic principle of mass conservation in fluid mechanics?
Show hintHide hint
Think about how fluids behave in control volumes.
Question 2.
Define incompressible flow.
Show hintHide hint
Look for the key difference in density behavior.
3Question 3.
What is the principle of mass conservation?
- Mass can be created
- Mass must remain constant
- Mass can disappear
Show hintHide hint
Think about the laws of physics regarding mass.
4Question 4.
Incompressible flow means density is?
- True
- False
Show hintHide hint
Remember the characteristics of incompressible versus compressible flow.
Question 5.
A cylindrical tank is filled with water and has a hole at the bottom through which water exits. Describe how you would apply mass conservation to determine how the water level changes over time.
Show hintHide hint
Make sure to set up your control volume correctly.
Question 6.
For a gas flowing through a converging nozzle, derive the change in density as the velocity increases.
Show hintHide hint
Identify relationships between pressure changes and velocity.
