In forced convection, the heat transfer depends on _______________?
Correct answer: A. Re, Pr
- A. Re, Pr
- B. Re, Gr
- C. Mainly Gr
- D. Re only
Explanation
Forced-convection correlations commonly express Nusselt number as a function of Reynolds and Prandtl numbers, such as Nu = f(Re, Pr). The Grashof number is primarily associated with natural convection.
