This successful textbook emphasizes the unified nature of all the disciplines of fluid mechanics as they emerge from the general principles of continuum mechanics. The different branches of fluid mechanics, always originating from simplifying assumptions, are developed according to the basic rule: from the general to the specific. The first part of the book contains a concise but readable introduction to kinematics and the formulation of the laws of mechanics and thermodynamics. The second part consists of the methodical application of these principles to technology. In addition, sections about thin-film flow and flow through porous media are included.
