15. Fluid Mechanics

Try these first

1. 1.

   What are the three types of control volumes?

   Hint

   Think about how they behave in space.

2. 2.

   What does the Reynolds transport theorem relate?

   Hint

   Consider mass and energy balance.

3. 3.

   What is the Reynolds transport theorem used for?

   • To calculate pressure
   • To relate system dynamics to control volume
   • To measure fluid density

   Hint

   It helps link concepts.

4. 4.

   True or False: The mass of a closed system can change.

   • True
   • False

   Hint

   Think about what conservation means.

5. 5.

   Design a control volume around a water pipe and identify the inflow and outflow rates. How would you ensure mass conservation?

   Hint

   Think about the balance between what comes in and goes out.

6. 6.

   Explain a scenario involving a ship in motion through a river. How is mass conserved in this dynamic system?

   Hint

   Consider the ship's impact on the water's surface.
