Question 1.
Define linear momentum equation in your own words.
Show hintHide hint
Focus on the concept of force and fluid movement.
Question 2.
What does the momentum flux correction factor (β) indicate?
Show hintHide hint
Think about fluid flow variations.
3Question 3.
What does the momentum flux correction factor (β) account for?
- Uniform velocity
- Non-uniform velocity
- Constant pressure
Show hintHide hint
Think about corrections for real-world flows.
4Question 4.
True or False: The linear momentum equation only applies in one dimension.
- True
- False
Show hintHide hint
Consider the nature of fluid movement.
Question 5.
A control volume experiences fluid inflow at 10 m/s with a density of 1,000 kg/m³. The outlet's velocity is 8 m/s. Calculate the net force acting on the control volume assuming no external forces. Consider the incoming density and pressure as well.
Show hintHide hint
Remember the balance between inflow and outflow!
Question 6.
If a large pipe has an increasing diameter, describe how the momentum flux will change throughout the pipe. Consider both sections of varying diameters.
Show hintHide hint
Think about how conservation applies in varying cross-sections.
