Which of the following is unimportant in forced convection ?
Correct answer: C. Grashoff number
- A. Reynolds number
- B. Prandtl number
- C. Grashoff number
- D. None of these
Explanation
Forced convection is governed mainly by Reynolds and Prandtl numbers, which represent flow regime and momentum-to-thermal diffusivity effects. The Grashof number measures buoyancy and is important mainly in natural convection.
