## Description

Physical Principles of Chemical Engineering covers the significant advancements in the understanding of the physical principles of chemical engineering. This book is composed of 12 chapters that describe chemical unit processes through analogy with the unit of operations of chemical engineering.

The introductory chapters survey the concept and principles of mass and energy balances, as well as the application of entropy. The next chapters deal with the probability and kinetic theories of gases, the physical aspects of solids, the different dispersed systems, and the principles and application of fluid dynamics. Other chapters discuss the property dimension and model theory; heat, mass, and momentum transfer; and the characteristics of multiphase flow processes. The final chapters review the model of rheological bodies, the molecular-kinetic interpretations of rheological behavior, and the principles of reaction kinetics.

This book will prove useful to chemical engineers.
