Question 1.
What is the formula for Reynolds number?
Show hintHide hint
What variables are involved in measuring flow?
Question 2.
Define Froude number.
Show hintHide hint
Think about flows influenced by gravity.
3Question 3.
What does Reynolds number indicate in fluid flow?
- Viscous forces dominate
- Inertial forces dominate
- Surface tension forces dominate
Show hintHide hint
Think about flow types.
4Question 4.
True or False: Froude number is the ratio of inertial to pressure forces.
- True
- False
Show hintHide hint
Remember what forces it compares.
Question 5.
Design an experiment where you could relate Reynolds and Froude numbers while observing a fluid in an open channel. What parameters will you focus on?
Show hintHide hint
Consider how you will keep gravity and inertia balanced.
Question 6.
You have two flow scenarios: one with a fluid having a high Reynolds number and one with high surface tension (Weber number). How would you adjust your design approach for both?
Show hintHide hint
Think about both inertia and surface effects!
