Incompressible fluids are fluids whose volume doesn’t change under pressure. This is typically true for liquids like water. Incompressible fluid mechanics studies how these fluids flow and behave. Key ideas include the continuity equation, which says that the amount of fluid remains constant in a flow and Bernoulli's principle, which connects pressure, speed and height in a flowing fluid. Understanding incompressible fluids helps design and optimise systems like water pipes, pumps and boat hulls. It explains fluid movement, how forces act on fluids and how fluids interact with surfaces. Engineers use this knowledge to create efficient and safe systems for various uses, from plumbing to marine and aviation technologies. This book provides comprehensive insights into the field of fluid mechanics. Also included in this book is a detailed explanation of the various concepts and applications of incompressible fluids. It will serve as a valuable source of reference for those interested in this field.
