Description

Introduction to Fluid Mechanics, Fifth Edition usesequations to model phenomena that we see and interact with every day. Placing emphasis on solved practical problems, this book introduces circumstances that are likely to occur in practice—reflecting real-life situations that involve fluids in motion. It examines the equations of motion for turbulent flow, the flow of a nonviscous or inviscid fluid, and laminar and turbulent boundary-layer flows. The new edition contains new sections on experimental methods in fluids, presents new and revised examples and chapter problems, and includes problems utilizing computer software and spreadsheets in each chapter.

The book begins with the fundamentals, addressing fluid statics and describing the forces present in fluids at rest. It examines the forces that are exerted on a body moving through a fluid, describes the effects that cause lift and drag forces to be exerted on immersed bodies, and examines the variables that are used to mathematically model open-channel flow. It discusses the behavior of fluids while they are flowing, covers the basic concepts of compressible flow (flowing gases), and explains the application of the basic concepts of incompressible flow in conduits. This book presents the control volume concept; the continuity, momentum, energy, and Bernoulli equations; and the Rayleigh, Buckingham pi, and inspection methods. It also provides friction factor equations for the Moody diagram, and includes correlations for coiled and internally finned tubes.

In addition, the author:

  • Concludes each chapter with a problems section
  • Groups the end-of-chapter problems together by topic
  • Arranges problems so that the easier ones are presented first

Introduction to Fluid Mechanics, Fifth Edition offers a basic analysis of fluid mechanics designed for a first course in fluids. This latest edition adds coverage of experimental methods in fluid mechanics, and contains new and updated examples that can aid in understanding and applying the equations of fluid mechanics to common, everyday problems.

Reviews

"… presents the application of mathematics to engineering in a very simple manner so that students can understand and follow it very easily. … The many newly added problems can be used to introduce students to the concept of Design of Experiments that satisfies one of the current ABET Student Outcomes. Use of both units in the main text rather than assigning problems in both units is a great help to the students when they go out to the industries."

—Mahesh C. Aggarwal, Ph.D, Gannon University, Erie, Pennsylvania, USA

"Well-written and well-illustrated text. Clear derivations and copious applications of the theory are presented. Well selected homework problems and many worked-out examples. Welcome addition to the collection of quality introductory fluid mechanics books."

—Eugene F. Brown, Professor Emeritus, Virginia Polytechnic Institute and State University, Blacksburg, USA

"This book provides a very good and thorough introduction to fluid mechanics at the undergraduate level. This revision offers more examples for the students to learn from as well as numerous homework problems to assign students. The author has a writing style that presents subjects in a very understandable way. The chapter on dimensional analysis is one of the most thorough and clear I have ever read."

—Amy Lang, University of Alabama, Tuscaloosa, USA

"… I can confirm that the fifth edition of the book provides a very good introduction to fluid mechanics fundamentals."

—Thanos Megaritis, Brunel University London, UK

"The book is very well written, and it provides a very thorough mathematical analysis that can easily be followed by engineering students. Very clear discussions on practical aspects of modeling in fluid flow analysis using non-dimensional parameters are made. The book is highly recommended to engineering students as well as other professionals involved in design and analysis of hydraulic systems."

—A. K. Oskouie, Illinois Institute of Technology, Chicago, USA
