The volume serves as a supplement to the established foundational book on fluid mechanics, providing a more in-depth treatment of the lecture material. The division of the chapters largely corresponds to that in the foundational volume: hydrostatics, kinematics, momentum theorem, Navier-Stokes equations, potential flow, vortex flow, boundary layer flow, and turbulent flow. The book concludes with discussions on pipe flows, flow around bodies, similarity laws, and numerical flow calculations. It includes numerous practical examples. Suitable for engineering students, physicists, and application-oriented mathematicians for self-study as well as for lecture support.
