Question 1.
What is natural convection?
Show hintHide hint
Think about how warm air behaves.
Question 2.
Define the Sherwood number.
Show hintHide hint
It’s a measure of mass transfer effectiveness.
3Question 3.
What causes natural convection?
- Chemical reactions
- Density differences
- Pressure differences
Show hintHide hint
Consider how warm fluids act.
4Question 4.
True or False: The Sherwood number increases with better mass transfer efficiency.
- True
- False
Show hintHide hint
Is it a direct correlation?
Question 5.
Evaluate the mass transfer scenario for a chemical spill in a lake considering Reynolds and Sherwood numbers.
Show hintHide hint
Connect flow behavior to mass transport principles.
Question 6.
Discuss how natural convection might vary in a stratified lake versus an unstratified river.
Show hintHide hint
Consider the density differences in both scenarios.
