ABSTRACT
Mass, momentum, and energy transfer in transient regimes follow at every instant the laws of Chapter 1. Changes in energy (or enthalpy) reflect changes of what is stored in matter. At every instant that real processes unfold, total entropy increases. The entropy increase signals a decrease in the quality of energy, the loss of which cannot be made up in a short time scale. This loss translates into a decrease of the capacity to perform work. The transient form of the laws and entropy-generation equations and elementary forms of relevant transport equations are introduced here. Simulation programs are included on the CD.
