Описание: The seventh edition of Fluid Mechanics sees some additions and deletions but no philosophical change. The basic outline of eleven chapters, plus appendices, remains the same. The triad of integral, differential, and experimental approaches is retained. Many problem exercises, and some fully worked examples, have been changed. The informal, student-oriented style is retained. A number of new photographs and figures have been added. Many new references have been added, for a total of 435. The writer is a firm believer in “further reading,” especially in the postgraduate years. The total number of problem exercises continues to increase, from 1089 in the first edition, to 1675 in this seventh edition. There are approximately 20 new problems added to each chapter. Most of these are basic end-of-chapter problems, classified according to topic. There are also Word Problems, multiple-choice Fundamentals of Engineering Problems, Comprehensive Problems, and Design Projects. The appendix lists approximately 700 Answers to Selected Problems. The example problems are structured in the text to follow the sequence of recommended steps outlined in Sect. 1.3, Problem-Solving Techniques.The Engineering Equation Solver (EES) is available with the text and continues its role as an attractive tool for fluid mechanics and, indeed, other engineering problems. Not only is it an excellent solver, but it also contains thermophysical properties, publication-quality plotting, units checking, and many mathematical functions, including numerical integration. The author is indebted to Sanford Klein and William Beckman, of the University of Wisconsin, for invaluable and continuous help in preparing and updating EES for use in this text. For newcomers to EES, a brief guide to its use is found on this book’s website.

Описание на русском
В седьмом издании "Механики жидкости" есть некоторые дополнения и исключения, но никаких глобальных изменений. Основной план одиннадцати глав, плюс приложения, остается прежним. Сохраняется триада интегрального, дифференциального и экспериментального подходов. Многие проблемные задачи и некоторые полностью отработанные примеры были изменены. Сохраняется неформальный, ориентированный на студентов стиль. Был добавлен ряд новых фотографий и рисунков. Было добавлено много новых ссылок, в общей сложности 435. Писатель твердо верит в “дальнейшее чтение”, особенно в аспирантуру. Общее число проблемных упражнений продолжает увеличиваться с 1089 в первом издании до 1675 в седьмом. В каждую главу добавлено около 20 новых задач. Большинство из них являются основными проблемами конца главы, классифицированными в соответствии с темой. Существуют также Проблемы со словом, основы множественного выбора инженерных задач, Комплексные задачи и Дизайн-проекты. В приложении содержится около 700 Ответов на Отдельные задачи. Примеры задач структурированы в тексте в соответствии с последовательностью рекомендуемых шагов, описанных в разделе. 1.3. Методы Решения задач.
