In forced convection, the Nusselt number is a function of ____________________?
Correct answer: A. Re and Pr
- A. Re and Pr
- B. Re and Gr
- C. Pr and Gr
- D. Re and Sc
Explanation
For forced convection, the Nusselt number is commonly correlated using Reynolds number for the flow regime and Prandtl number for the relative momentum and thermal diffusivities. Hence Nu is a function of Re and Pr.
