Question 1.
Define linear momentum in your own words.
Show hintHide hint
Think of how much 'motion' an object has.
Question 2.
What is a control volume?
Show hintHide hint
Consider a box around a flowing fluid.
3Question 3.
What does the Reynolds Transport Theorem relate?
- Changes in the volume only
- Calculation of momentum within a control volume
- Friction in fluids
Show hintHide hint
Think of it as connecting motion inside a box.
4Question 4.
True or False: Surface forces include gravitational forces acting on fluid.
- True
- False
Show hintHide hint
Remember how gravity influences all particles equally.
Question 5.
A cylindrical vessel has water flowing in and out unevenly through different ports. Describe how you would calculate the net momentum change with provided velocities and corrections.
Show hintHide hint
Draw a visual for clearer flow relationships.
Question 6.
If a bridge pier is subjected to different flow speeds around it due to an approaching current, how would you compute the forces acting on it using momentum principles?
Show hintHide hint
Use diagrams to visualize pressure effects and flow paths.
