13.1.8. Conservation of Momentum

Try these first

1. 1.

   Define what a control volume is in fluid mechanics.

   Hint

   Think about where fluid interacts with boundaries.

2. 2.

   What is the conservation of momentum?

   Hint

   Consider applications in fluid motion.

3. 3.

   What does the conservation of momentum state?

   • It can change over time
   • It remains constant in a closed system
   • It is only applicable to solids

   Hint

   Consider closed systems in fluid dynamics.

4. 4.

   Is a control volume fixed in space?

   • True
   • False

   Hint

   Reflect on dynamic systems.

5. 5.

   In a pipe with varying diameters, how would you calculate the change in fluid velocity and momentum flow at different points?

   Hint

   Consider the conservation of mass.

6. 6.

   Design a problem where you calculate the lift force on an airfoil using momentum conservation principles. Include diagrams.

   Hint

   Focus on pressure differences above and below the wing.
