Revised and updated, this text provides details on intermediate concepts of potential, viscous, incompressible and compressible flow. Material is broad-based, covering a range of topics in an introductory manner, concentrating on the classic results rather than attempting to include the most recent advances in the subject. This new edition features expanded treatment of boundary layer flows, a new chapter dealing with buoyancy-driven flows, and new problems at the end of each chapter. A solutions manual is available (0-07-015001-X).
