Summary:

This book provides the fundamental knowledge allowing students in engineering and natural sciences to enter fluid mechanics and its applications in various fields where fluid flows need to be dealt with. This textbook is written for the introductory course of fluid mechanics for students at the undergraduate and postgraduate levels. Volume 1 of this textbook contains seven chapters to help build the basic understanding of the subject matter. It adequately covers the properties of fluids, pressure and its measurement, hydrostatic forces on surface, buoyancy, and floatation, kinematics of fluid motion, dynamics of fluid flow, and dimensional and model analysis. The concepts are supported by numerous solved examples and multiple-choice questions to aid self-learning in students. The textbook also contains illustrated diagrams for better understanding of the concepts. The book is extremely useful for the undergraduate and postgraduate students of engineering and natural sciences.
