In natural convection heat transfer, the correlating parameter is the_______________________?
Correct answer: C. Grashoff number
- A. Graetz number
- B. Eckert number
- C. Grashoff number
- D. Bond number
Explanation
Natural convection is driven by buoyancy produced by density differences, and the Grashof number compares buoyancy forces with viscous forces. Graetz and Eckert numbers describe other transport effects.
