4.1. Summary of Fluid Mechanics 2

Try these first

1. 1.

   Define the Reynolds Transport Theorem in your own words.

   Hint

   Think about how we analyze systems vs. control volumes.

2. 2.

   State the continuity equation.

   Hint

   Remember the concept of conservation of mass.

3. 3.

   What does the Reynolds Transport Theorem relate to?

   • Conservation of mass
   • Force analysis
   • Energy conservation

   Hint

   Consider how mass is analyzed in different contexts.

4. 4.

   True or False: The continuity equation states that mass can be created within a control volume.

   • True
   • False

   Hint

   Rethink conservation principles.

5. 5.

   A water pipe has an inflow of 10 L/s and an outflow of 8 L/s. What is the change in water volume inside the pipe over 5 minutes?

   Hint

   Remember to convert time to seconds.

6. 6.

   If a fluid jet has a diameter of 10 cm and exits a nozzle at 5 m/s, calculate the mass flow rate given the fluid density is 800 kg/m³.

   Hint

   Don't forget to use the correct formula for area!
