Question 2.
Define extensive properties in your own words.
Show hintHide hint
Think of total measurable quantities.
3Question 3.
What principle states that energy cannot be created or destroyed?
- Conservation of Mass
- Conservation of Energy
- Conservation of Momentum
Show hintHide hint
Think of energy being transformed, like batteries powering devices.
4Question 4.
True or False: Control volumes must be deformable.
- True
- False
Show hintHide hint
Consider the basic definition of a control volume in mechanics.
Question 5.
Suppose you have a control volume with constant density and a steady-state flow. How would you apply RTT in analyzing the inflow and outflow?
Show hintHide hint
Use steady-state conditions to simplify the analysis.
Question 6.
Design a pumping system for a fluid under variable density. How will the principles of RTT assist you?
Show hintHide hint
Remember to factor how density affects total energy in your calculations.
