Fluid mechanics, the study of how fluids behave and interact under various forces and in various applied situations—whether in the liquid or gaseous state or both—is introduced and comprehensively covered in this widely adopted text. Revised and updated by Dr. David Dowling, Fluid Mechanics, 5e is suitable for both a first or second course in fluid mechanics at the graduate or advanced undergraduate level.

Key Features

  • Along with more than 100 new figures, the text has been reorganized and consolidated to provide a better flow and more cohesion of topics.
  • Changes made to the book's pedagogy in the first several chapters accommodate the needs of students who have completed minimal prior study of fluid mechanics.
  • More than 200 new or revised end-of-chapter problems illustrate fluid mechanical principles and draw on phenomena that can be observed in everyday life


Senior undergraduate/graduate students in mechanical, civil, aerospace, chemical and biomedical engineering; Senior undergraduate/graduate students in physics, chemistry, meteorology, geophysics, and applied mathematics
