E)None of the above

Question

Quizplus · Accepted Answer

In the case of natural convection, the Nusselt number is a function of the Grashof number and the Prandtl number. This is because the Grashof number characterizes the buoyancy-driven flow (natural convection), and the Prandtl number represents the fluid's thermal and momentum diffusivity ratio.
