20.1.1. Conservation of Momentum and its Applications

Try these first

1. 1.

   Define conservation of momentum.

   Hint

   Think about momentum in terms of mass and velocity.

2. 2.

   What are body forces?

   Hint

   Consider forces that affect the entire fluid's volume.

3. 3.

   What is the principle of conservation of momentum?

   • A principle stating total momentum is constant
   • A principle stating total energy is constant
   • A principle stating force is constant

   Hint

   It relates to mass and velocity.

4. 4.

   True or False: Body forces are only pressure forces acting on a surface.

   • True
   • False

   Hint

   Think about different types of forces in fluid dynamics.

5. 5.

   A cylindrical tank has water flowing through it at varying rates across its inlets. If the velocity profile is given, how would you calculate the necessary momentum flux corrections?

   Hint

   Utilize integration techniques to find total momentum over the control volume.

6. 6.

   Describe a practical application of conservation of momentum in designing a bridge and how you would analyze fluid flow effects on the structure.

   Hint

   Create a model diagram for better visualization of forces acting on the structure.
