The fifth edition of "Fluid Mechanics" continues the tradition of precision, accuracy, accessibility, and strong conceptual presentation. This new edition retains its basic organization. The three approaches - integral, differential, and dimensional analysis - are treated separately, providing the conceptual foundation of fluid mechanics. Chapters on ducts, immersed bodies, potential flow, compressible flow, open channels, and turbomachinery show the major applications of the field. The new edition includes a systematic problem solving methodology for readers to follow. New chapter examples and approximately 250 new chapter problems have been added. The EES (Engineering Equation Solver) software is included, free to users, as a means to model and solve problems on the computer. A new appendix offers a brief review of mathematical tools.
