A Connection Between Transport Phenomena and Thermodynamics
Although students take courses in transport phenomena
and thermodynamics, they probably do not ask whether these two
subjects are related. Here we give an answer to that question.
Specifically we give relationships between the equations of change
for total energy, internal energy, and entropy of transport
phenomena and key equations of equilibrium thermodynamics. It is
revealing to see how the irreversible processes of heat conduction
and viscous flow in going from one thermodynamic state to another
are accommodated in the derivation of dUTdSpdV.
