2. Conservation of Momentum

Try these first

1. 1.

   What does Reynolds Transport Theorem relate to in fluid mechanics?

   Hint

   Think about how we analyze systems versus volumes.

2. 2.

   Define the continuity equation.

   Hint

   Consider the balance of entering and leaving mass.

3. 3.

   What does the Reynolds Transport Theorem help to analyze?

   • Momentum only
   • Mass only
   • Both mass and momentum

   Hint

   Think about what properties matter in fluid flow.

4. 4.

   True or False: The continuity equation applies only to compressible fluids.

   • True
   • False

   Hint

   Consider if mass conservation applies regardless of fluid density.

5. 5.

   A cylindrical tank with a radius of 2m discharges water at a rate of 0.5 m³/s. Calculate the height drop in the tank over 10 minutes.

   Hint

   How do volume and area relate to height in a cylindrical tank?

6. 6.

   Calculate the force on a wall when a nozzle discharges fluid at 3 m/s with a cross-sectional area of 0.01 m².

   Hint

   Use mass flow rate and Newton's Second Law.
