Question 1.
What is a stress tensor?
Show hintHide hint
Think about force per area as a concept.
Question 2.
Define 'control volume' in fluid mechanics.
Show hintHide hint
Consider it as a theoretical space where we observe fluids.
3Question 3.
What does a stress tensor represent?
- Force per unit volume
- Force per unit area
- Velocity per unit area
Show hintHide hint
Remember what stress means in fluid dynamics.
4Question 4.
True or False: Control volumes only include surface forces.
- True
- False
Show hintHide hint
What types of forces do we analyze in control volumes?
Question 5.
A tank has an outlet pipe discharging water at a specific velocity. Calculate the momentum flux at the outlet considering velocity distribution is uniform.
Show hintHide hint
What do you know about flow rates?
Question 6.
Given a fluid with varying densities and a changing velocity profile, derive the forces acting on the control volume.
Show hintHide hint
Consider the impact of gravity and pressure distribution.
