1. Explain the physical nature of natural convection. How does it differ from forced convection?
2. Explain the genesis of the Grashof number, Gr. What does it represent? Why is it important in our study of natural convection?
3. Describe the process you would follow to determine the correct empirical correlation for a horizontal plate natural convection problem.
4. What analysis changes do we need to make for natural convection in enclosed spaces?
5. What do we have to take into account when we have combined forced and natural convection? How does this change our heat transfer analysis?
