Linear Transport Relations (LTR)

Much of Transport Phenomena deals with the exchange of momentum, mass, or heat between two (or many) objects. Often, the most mathematically simple way to consider how and how fast exchanges take place is to look at driving forces and resistances.

In momentum transport, we are interested in driving forces that arise from differences in pressure and/or velocity.

In heat and mass transport, our driving forces arise from differences in concentration and temperature.
