Momentum, Heat, and Mass Transfer

In this book, we will examine the transport of momentum, heat, and mass through a system. Thermodynamics deals with systems at equilibrium and transitions between equilibrium states. It can tell us things like the properties of various states or the criteria for equilibrium. For example using thermodynamics, we can prove that, for all positions r and rJ in a system, equilibrium is given by (N.B.: The following equations neglect the presence of gravity)
