Fox and McDonald's Introduction to Fluid Mechanics

by Robert W. Fox, Alan T. McDonald, John W. Mitchell

Overview

Through ten editions, Fox and McDonald's Introduction to Fluid Mechanics has helped students understand the physical concepts, basic principles, and analysis methods of fluid mechanics. This market-leading textbook provides a balanced, systematic approach to mastering critical concepts with the proven Fox-McDonald solution methodology. In-depth yet accessible chapters present governing equations, clearly state assumptions, and relate mathematical results to corresponding physical behavior. Emphasis is placed on the use of control volumes to support a practical, theoretically-inclusive problem-solving approach to the subject.

Each comprehensive chapter includes numerous, easy-to-follow examples that illustrate good solution technique and explain challenging points. A broad range of carefully selected topics describe how to apply the governing equations to various problems, and explain physical concepts to enable students to model real-world fluid flow situations. Topics include flow measurement, dimensional analysis and similitude, flow in pipes, ducts, and open channels, fluid machinery, and more. To enhance student learning, the book incorporates numerous pedagogical features including chapter summaries and learning objectives, end-of-chapter problems, useful equations, and design and open-ended problems that encourage students to apply fluid mechanics principles to the design of devices and systems.

Editorial Reviews

Text for an introductory one- or two-semester course at the junior or senior level emphasizes the physical concepts of fluid mechanics and analysis methods, beginning from basic principles. Major additions to this edition (third, 1985) include a new chapter on fluid machinery, a new section on supersonic channel flow, and a large number of new homework problems. Introductory courses in rigid-body dynamics and math through integral calculus are necessary prerequisites. Annotation c. Book News, Inc., Portland, OR (booknews.com)
