The Grashof number (Gr) is the ratio of the buoyancy to the viscous force acting on a fluid.
In mass transfer, temperatures will be replaced with concentration.

Graetz Number
In fluid dynamics, the Graetz number (Gz) characterizes laminar flow in a conduit. It is expressed as: In mass transfer, it is the ratio of momentum diffusivity to mass diffusivity.
