Flux is two separate simple and ubiquitous concepts throughout physics and applied mathematics. Within a discipline, the term is generally used ... more

In the context of heat transfer. the Bejan number is the dimensionless pressure drop along a channel of length.

In the context of mass transfer, the Bejan number is the dimensionless pressure drop along a channel of length.

In fluid mechanics, the Reynolds number is used to help predict if flow will be laminar or turbulent. We know that flow in a very smooth tube, streamlined ... more
