Question 1.
Define momentum in your own words.
Show hintHide hint
Think about how mass and speed work together.
Question 2.
What is a control volume?
Show hintHide hint
It's the area we focus our calculations on.
3Question 3.
What principle describes the conservation of momentum?
- Mass remains constant
- Momentum is constant in a closed system
- Energy is conserved
Show hintHide hint
Focus on the system's isolation.
4Question 4.
True or False: The Reynolds transport theorem only applies to steady flows.
- True
- False
Show hintHide hint
Consider all flow conditions.
Question 5.
A fluid flows in a pipe into a tank with varying diameters. Given different velocities at each section, calculate the overall momentum entering the tank.
Show hintHide hint
Remember to factor in the cross-sectional area at each diameter.
Question 6.
In a system with turbulent flow, the density varies significantly. Apply the momentum flux correction factor to find the accurate momentum transfer.
Show hintHide hint
Adjust calculations based on observed flow patterns.
