This book is a basic introduction to the subject of fluid mechanics and is intended for undergraduate and beginning graduate students of science and engineering. There is enough material in the book for at least two courses. No previous knowledge of the subject is assumed, and much ofthe text is suitable in a first course on the subject. On the other hand, a selection of the advanced topics could be used in a second course. Particular effort has been made to make the presentation clear and accurate and at the same time easy enough for students.
A survey of the available texts revealed the need for a book with a balanccd view, dealing with currently relevant topics, and at the same time easy enough for students. The available texts can perhaps be divided into three broad groups. One type, written primarily for applied mathematicians, deals mostly with classical topics such as irrotational and laminar flows, in which analytical solutions are possible. A sccond group of books emphasizes engineering applications, concentrating on flows in such systems as ducts, open channels, and airfoils. A third type of text is narrowly focused loward applications to largc-scale gcmphysical systems, omitting small-scale processes which are equally applicablc to geophysical system as well as laboratory-scale phenomena. Several of thcsc geophysical fluid dynamics texts are also writlen primarily for researchers and arc therefore rather difficult for students.

Several important changes in emphasis have been made in this revision. The most extensive change is in the handling of compressible flow. In general, there is no fixed pattern for the election of thermodynamics before fluid mechanics throughout the engineering colleges. The treatment of compressible fluids should not repeat an appreciable amount of work normally covered in thermodynamics but should either introduce this work or supplement it. Owing to the limited class time in a course on fluids, thermodynamic topics have been restricted to perfect gases with constant specific heats. The treatment of losses conforms generally to thermodynamic concepts. These changes have caused minor changes in the fluid properties treatment, major changes in fluid concepts and basic equations, and a new treatment of the chapter on compressible flow.
As the first courses in statics and dynamics are now being taught with vectors in-many schools, they have been introduced where appropriate. Most of the fluid treatment is one-dimensional and hence neither requires nor benefits from vectors. In two- and three-dimensional flow, however,
they are used for derivations of continuity, momentum, and Euler’s equation. The chapter on dimensional analysis has been strengthened and moved forward to Chapter 4 for greater emphasis. The chapter on fluid statics has been shortened somewhat, and the viscous effects treatment, Chapter 5, has been shortened, with compressible examples and applications removed to Chapter 6.
