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.
