Fluid Mechanics third edition

Fluid Mechanics third edition : Several important changes in emphasis have been made in this revision. The most. extensive change is in the handling of compressible flow. In general, there is no fixed pattern for the election of thermodynamics before fluid mechanics throughout the engineering colleges. The treat- ment of compressible fluids should not repeat an appreciable amount of work normally covered in thermodynamics but should either introduce this work or supplement it.

Owing to the limited class time in a course on fluids, thermodynamic topics have been restricted to perfect gases with constant specific heats. The treatment of losses conforms generally to thermodynamic concepts.

These changes have caused minor changes in the fluid properties treatment, major changes in fluid concepts and basic equations, and a new treatment of the chapter on compressible flow. As the first courses in statics and dynamics are now being taught with vectors in-many schools, they have been introduced where appropriate. Most of the fluid treatment is one-dimensional and hence neither requires nor benefits from vectors. In two- and three-dimensional flow, however, they are used for derivations of continuity, momentum, and Euler’s equation.
