1. 1.

   What does the Reynolds Transport Theorem relate?

   Hint

   Think about how we analyze fluid systems.

2. 2.

   Define conservation of mass.

   Hint

   Consider a closed container.

3. 3.

   What does the continuity equation express?

   • Mass is conserved
   • Mass can be created
   • Mass is lost over time

   Hint

   Reflect on conservation principles.

4. 4.

   True or False: The Reynolds Transport Theorem only applies to compressible fluids.

   • True
   • False

   Hint

   Consider the general applicability of fluid dynamics.

5. 5.

   A fluid flowing through a pipe has varying diameters. If the velocity at one section is 3 m/s with an area of 0.5 m², and another section has an area of 0.2 m², what is the velocity at the second section?

   Hint

   Make sure to rearrange the equation properly!

6. 6.

   A water jet with a flow rate of 0.1 m³/s strikes a vertical wall at a velocity of 15 m/s. Calculate the force exerted on the wall.

   Hint

   Apply the mass flow rate principles.
