Those who have developed our current knowledge of fluid mechanics are too numerous to mention. There are also my mentors, students, and colleagues who have studied and taught fluid mechanics for over 30 years. The most influential of these people has undoubtedly been my mentor, Hunter Rouse.
However, I would like to give more direct credit to Mrs.Pat Roberts, who not only encouraged me to write this book but also typed the final results; to Mrs.Val Gray, who drew numerous diagrams; and to Dr.R.H.Spiegel, who improved the first draft through constructive criticism. Finally, I would like to dedicate this book to the memory of my son Steve.
About the Book
Fluid mechanics is a traditional foundation of civil engineer education. As the numerous books on the subject suggest, there are many different ways to introduce fluid mechanics to students. This text is the result of lectures I have given to civil engineering students at the University of Canter bury over the past 24 years. The book combines what many teachers would call basic fluid mechanics with applied hydraulics.
Chapter1 includes an introduction to fluid and flow properties and a review of vector calculus in preparation for Chapter2, which includes the derivation of the governing equations of fluid motion. Chapter3 covers the usual topics in hydro statics, including pressure distributions, forces on planar and curved surfaces, stability of floating bodies, and rigid body acceleration of fluids.
Chapter4 introduces the use of the control volume equation in one-dimensional fluid calculations. Chapter5 outlines the problem of solving partial differential equations for velocity and pressure distributions across a fluid in motion, and Chapters6 through 9 provide details for performing these calculations for flows requiring calculations of irregular, laminar and turbulent, boundary-laminar, and secondary flows, as well as lift and drag forces.
Chapter10 introduces dimensional analysis and model similitudes, but a solid understanding of Chapters1through9 is necessary for students to understand and effectively use this very important tool for experimental work. Chapters11 through 14 deal with application areas traditionally important in hydraulic engineering.
Chapters11,12, and13 introduce property methods for solving water hammer problems in steady pipe flow, steady open channel flow, and unsteady pipe flow, respectively, while Chapter14 builds on Chapter13 and uses properties to tackle the more challenging problem of unsteady flow in open channels.
