## About the Book

This Book presents a thorough and comprehensive treatment of both the basic as well as the more advanced concepts in Fluid Mechanics. The entire range of topics comprising fluid mechanics has been systematically organised and the various concepts are clearly explained with the help of several solved examples.

Apart from the fundamental concepts, the book also explains Fluid Dynamics, Flow Measurement, Turbulent and Open Channel Flows and Dimensional and Model Analysis. Boundary Layer Flows and Compressible Fluid Flows have been suitably highlighted.

Turbines, pumps and other hydraulic systems including circuits, valves, motors and Ram have also been explained. The book provides 225 fully worked out examples and more than 1600 questions including numerical problems and objective questions. The book would serve as an exhaustive text for both undergraduate and post- graduate students of Mechanical, Civil and Chemical Engineering. AMIE and competitive examination candidates as well as practising engineers would also find this book very useful.
