Try these first

1. 1.

   Define conservation of momentum.

   Hint

   Consider the principle of closed systems in physics.

2. 2.

   What does the Reynolds transport theorem relate?

   Hint

   Think about how quantities move in and out of a defined space.

3. 3.

   What is the core principle of momentum conservation?

   • Momentum increases with velocity
   • Total momentum remains constant in a closed system
   • Momentum is always conserved

   Hint

   Think about situations where external influences are absent.

4. 4.

   True or False: The Reynolds transport theorem is only applicable for steady flows.

   • True
   • False

   Hint

   Consider how this theorem connects different flow conditions.

5. 5.

   You have a fluid flowing through a pipe with a varying diameter. If the velocity in the wider section is known, how would you determine the velocity in the narrower section while considering conservation of momentum?

   Hint

   Focus on the volumetric flow rate consistency across different sections.

6. 6.

   Assuming two different fluids are mixed in a controlled volume; if their properties vary, how can you compute the resulting momentum?

   Hint

   Use individual flow equations for each fluid before combining.
