Introduction to Fluid Mechanics, Fifth Edition uses equations 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.
