In this second edition of Fluid Mechanics, which is a revised and substantially expanded version of the first edition, several new topics such as Open Channel Flow, Hydraulic Turbines, Hydraulic Transients, Flow Measurements, Pumps and Fans, and One-Dimensional Viscous Flow have been added. After a comprehensive introduction, the book goes on to present a thorough analysis of such topics as fluid statics, fluid kinematics, analysis of finite control volumes and the mechanical energy equation. It also provides a compre- hensive description of, among others, one-dimensional viscous flow, dimensional analysis, two-dimensional flow of ideal fluids, and normal and oblique shocks. The summary and exercises provided at the end of each chapter enable the student to recapture the topics presented. The worked-out examples help the reader in comprehending the problems discussed. The book is a happy fusion of theory and applications and should prove to be an ideal text for undergraduate students of civil and mechanical engineering and as a ready reference for the first-level postgraduate students.
