The textbook "Fluid Mechanics" provides a clear introduction to the fundamentals, basic equations, and solution methods of fluid mechanics and has become a standard work in fluid mechanics education. It systematically addresses the introduction of fluid mechanics software that development engineers encounter in the industry. Scientists will find the physical principles of fluid flow, which are particularly important for meteorology and geophysics. The current edition includes additional application examples and substantial reader feedback has been taken into account. Suitable for engineers and scientists.
