Fluid mechanics, the study of how fluids behave and interact under various forces and in various applied situations - whether in the liquid or gaseous state or both - is introduced and comprehensively covered in this widely adopted text. Fully revised and updated with the addition of a new chapter on biofluid mechanics, "Fluid Mechanics, Fourth Edition" is suitable for both a first or second course in fluid mechanics at the graduate or advanced undergraduate level. The leading advanced general text on fluid mechanics, Kundu & Cohen's "Fluid Mechanics, 4e" now includes a free copy of the DVD "Multimedia Fluid Mechanics, second edition". With the inclusion of the DVD, students can gain additional insight about fluid flows through nearly 1,000 fluids video clips, can conduct flow simulations in any of more than 20 virtual labs and simulations, and can view dozens of other new interactive demonstrations and animations, thereby enhancing their fluid mechanics learning experience. It includes updates to several chapters and sections, including Boundary Layers, Turbulence, Geophysical Fluid Dynamics, Thermodynamics and Compressibility. It is fully revised and updated chapter on Computational Fluid Dynamics. It features new chapter on Biofluid Mechanics by Professor Portonovo Ayyaswamy, the Asa Whitney Professor of Dynamical Engineering at the University of Pennsylvania. New Visual Resources appendix provides a list of fluid mechanics films available for viewing online. This title now includes free "Multimedia Fluid Mechanics, 2e" DVD.
