A non-dimensional number generally associated with natural convection heat transfer is Correct Answer Grashoff number

The Grashof number (Gr) is a dimensionless number in fluid dynamics and heat transfer which approximates the ratio of the buoyancy to the viscous force acting on a fluid.It frequently arises in the study of situations involving natural convection and is analogous to the Reynolds number.
