Question 1.
What does the Reynolds number represent?
Show hintHide hint
Think about forces affecting fluid flow.
Question 2.
Define geometric similarity.
Show hintHide hint
Keywords are 'proportional dimensions'.
3Question 3.
What does the Reynolds number relate to?
- Viscous forces
- Gravitational forces
- Inertial forces
Show hintHide hint
Think about the fluid's viscosity.
4Question 4.
True or False: Dynamic similarity only involves matching length and time scales.
- True
- False
Show hintHide hint
Consider what forces implications it has.
Question 5.
Model a water tank for an experiment to study free surface flow. What parameters would you consider for geometric, kinematic, and dynamic similarity?
Show hintHide hint
Think about how you would scale the tank.
Question 6.
Explain how the choice of repeating variables can change the outcomes of dimensional analysis. Provide an example.
Show hintHide hint
Reflect on how different variables can yield different results.
