14.1.2. Energy Conservation Principles

Try these first

1. 1.

   What is an extensive property in fluid mechanics?

   Hint

   Think about properties that change with the size of a system.

2. 2.

   Define an intensive property.

   Hint

   Consider what stays the same regardless of the quantity.

3. 3.

   What is an example of an extensive property?

   • Specific energy
   • Total energy
   • Velocity

   Hint

   Think about what increases with larger amounts of mass.

4. 4.

   True or False: Specific energy is an extensive property.

   • True
   • False

   Hint

   Recall the definitions of extensive and intensive properties.

5. 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?

   Hint

   Consider both conservation of mass and energy together.

6. 6.

   Given a fluid with varying density flowing through a pipe, describe how to utilize intensive properties to assess flow characteristics.

   Hint

   Remember relations between density, velocity, and specific energy.
