Fluid Mechanics provides a comprehensive treatment of the essentials of the subject for students of mechanical, chemical or civil engineering and building services or environmental engineering. Well established as the key textbook in the field, this third edition has been substantially updated and improved in line with today's courses. As in previous editions the reader is guided from the general to the particular, introduced to the basic "building block" equations and shown their application and development through a series of increasingly specialized topics. The breadth of coverage is wide-ranging, covering both bounded and free surface flow conditions, and fluid mechanics is treated as a truly cross-disciplinary topic within engineering.
