Question 1.
What is an extensive property in fluid mechanics?
Show hintHide hint
Think about properties that change with the size of a system.
Question 2.
Define an intensive property.
Show hintHide hint
Consider what stays the same regardless of the quantity.
3Question 3.
What is an example of an extensive property?
- Specific energy
- Total energy
- Velocity
Show hintHide hint
Think about what increases with larger amounts of mass.
4Question 4.
True or False: Specific energy is an extensive property.
- True
- False
Show hintHide hint
Recall the definitions of extensive and intensive properties.
Question 5.
A tank of water is emptied at a constant rate while simultaneously being filled at a different rate. How does energy conservation apply, and how would you utilize the Reynolds Transport Theorem to analyze this scenario?
Show hintHide hint
Consider both conservation of mass and energy together.
Question 6.
Given a fluid with varying density flowing through a pipe, describe how to utilize intensive properties to assess flow characteristics.
Show hintHide hint
Remember relations between density, velocity, and specific energy.
