Intended for aeronautics students, this text will also be helpful to practicing engineers and scientists who work on problems involving the aerodynamics of compressible fluids. The book covers general principles of gas dynamics to provide a working understanding of the essentials of gas flow, explaining introductory concepts from thermodynamics including entropy, reciprocity relations, equilibrium conditions, the law of mass action and condensation, methods of measurement, transonic flow, and effects of viscosity and conductivity. This is an unabridged republication of a work published by John Wiley & Sons, Inc., New York, 1957. Annotation c. Book News, Inc., Portland, OR (booknews.com)
