Question

In natural convection nussent no is function of

Answer 1

In heat transfer at a boundary (surface) within a fluid, theNusselt number (Nu) is the ratio of convective to conductive heat transfer across (normal to) the boundary. ... A Nusselt numberclose to one, namely convectionand conduction of similar magnitude, is characteristic of "slug flow" or laminar flow.
