A flux of charges is induced when a driving force in the form of an electrical field is applied over a medium or a material that is able to conduct electrical charges. An electrical field…

A volume flux is induces when a driving force in the form of a pressure difference is applied. The flux of volume is proportional to this driving force and the proportionality constant is called the…

Momentum can be transferred when a driving force in the form of a velocity difference exists. Transport of Momentum can be explained by describing the situation sketched in below Figure, which shows an example of…

Energy in the form of heat can be transported when a driving force in the form of a temperature difference is applied. The flux of heat is proportional to the applied driving force and the…

Diffusion of mass is also known as Transport of Mass or mass diffusion, concentration diffusion or ordinary diffusion. We are talking about molecular mass transport taking place as diffusion of a component A through a…

Driving forces are specified and flux equations are given for different kinds of transport. SI units for the phenomenological coefficients and the fluxes are given as well together with the common names for the different…

Things only move when they are forced to move! A bicycle only moves when a force is applied in the form of pedaling. A cloud on the sky only moves when a force is applied…
