Preface to the Second Edition
This book Basic Fluid Mechanics is revised and enlarged by the addition of four chapters
on Hydraulic Machinery and is now titled as Fluid Mechanics and Machinery. The authors
hope this book will have a wider scope.
This book will be suitable for the courses on Fluid Mechanics and Machinery of the vari-
ous branches of study of Anna University and also other Indian universities and the Institution
of Engineers (India).
Professor Obert has observed in his famous treatise on Thermodynamics that concepts
are better understood by their repeated applications to real life situations. A firm conviction of
this principle has prompted the author to arrange the text material in each chapter in the
following order.
In the first section after enunciating the basic concepts and laws, physical and
mathematical models are developed leading to the formulation of relevant equations for the
determination of outputs. Simple and direct numerical examples are included to illustrate the
basic laws. More stress is on the model development pared to numerical problems.
A section titled “SOLVED PROBLEMS” comes next. In this section more involved deri-
vations and numerical problems of practical interest are solved. The investigation of the effect
of influencing parameters for plete spectrum of values is attem
