Engineering Fluid Mechanics, 12th edition, guides students from theory to application, emphasizing skills like critical thinking, problem solving and modeling to apply fluid mechanics concepts to solve real-world engineering problems. The essential concepts are presented in a clear and concise format, while abundant illustrations, charts, diagrams, and examples illustrate complex topics and highlight the physical reality of fluid dynamics applications. The text emphasizes on technical derivations, presenting derivations of main equation in a step-by-step manner and explaining their holistic meaning in words. The Wales-Wood Model is used throughout the text to solve numerous example problems. This International Adaptation comes with some updates that enhance and expand certain concepts and some organizational changes. The edition provides a wide variety of new and updated solved problems, real-world engineering examples, and end-of-chapter homework problems and has been completely updated to use SI units. The text, though written from civil engineering perspective, adopts an interdisciplinary approach which makes it suitable for engineering students of all majors who are taking a first or second course in fluid mechanics.
