14.3.2. Integration Over Control Surfaces

Try these first

1. 1.

   What are the three conservation laws discussed?

   Hint

   Remember the acronym MOM.

2. 2.

   Define extensive properties in your own words.

   Hint

   Think of total measurable quantities.

3. 3.

   What principle states that energy cannot be created or destroyed?

   • Conservation of Mass
   • Conservation of Energy
   • Conservation of Momentum

   Hint

   Think of energy being transformed, like batteries powering devices.

4. 4.

   True or False: Control volumes must be deformable.

   • True
   • False

   Hint

   Consider the basic definition of a control volume in mechanics.

5. 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?

   Hint

   Use steady-state conditions to simplify the analysis.

6. 6.

   Design a pumping system for a fluid under variable density. How will the principles of RTT assist you?

   Hint

   Remember to factor how density affects total energy in your calculations.
