About this eBook
Preface to the Second Edition The aim of this revised and enlarged edition is same as that of the earlier edition, as to intend primarily for easiness in understanding of the subject of Fluid Mechanics and Machinery and to raise the standard of the reader, step by step in understanding the concepts of Fluid Mechanics and its applications in fluid machinery, with clear pictorial explanations. In this edition, all the content has been revised thoroughly and modified. Apart from it the errors in previous edition have also been rectified. Additional information wherever necessary has been added. Some additional problems are also been included. In this edition, a new topic Buoyancy and Floatation has been added as an extension of Chapter 4. Suggestions and comments from the readers for further editions of the text will be greatly appreciated.

Preface to the First Edition This book is intended primarily for easiness in understanding of the subject of Fluid Mechanics and Machinery. It is designed to raise the standard of the reader, step by step in understanding the concepts of fluid mechanics and its application in fluid machinery, with clear pictorial explanation. The contents are been developed in transition from basics of simple chapters to complexity of the remaining chapters, including the fundamental formulae used for deriving equations, without leaving the connection between chapters and their applications. An attempt of more number of diagrams are been introduced for enhancing easiness in understanding of the changes and assumptions taken in derivations. Important formulae including their units, important points and values to be remembered, are been given in a tabular format at the end of each chapter, so as to provide quick reference of these, by the reader. This book has been organized in two parts, namely, 1. Fluid Mechanics and 2. Fluid Machinery, so that the reader can have the flexibility to switch over to the subject of Fluid mechanics or Fluid mechanics application in machinery, as per his necessity and need. Part 1 of this book, structured on the basics and fundamental theories behind fluids Liquids and Gasses and consists of nine chapters, Chapter 1 Discusses concepts of Fluid properties like their density, specific weight, specific volume, etc. and also explained fluid behavioral aspects like viscosity, surface tension, cohesion and adhesion phenomenon, capillarity effects. The fluid classification is provided basing on their behavior like Newtonian and non-Newtonian fluids. The important property of fluid, like pressure, which is of main concern in case of fluids and its measurements, when in hydrostatic condition, based on Pascal s law manometers is dealt in Chapters 2 and Chapter 3 describes the hydrostatic forces arise on the surface immersed in fluids and hydrostatic condition. Chapters 4 and 5 deals with the Kinematics and Dynamics fluid flows respectively, considering Circulation and Vorticity in flow and assuming the flow to be continuous and incompressible. Equation of Continuity and Bernoulli s equation has been derived and application of Bernoulli s equation in devices like Venturimeter, Orifice meter and Pitot tube are discusses. Moreover, vortex motion is also explained. The viscous flow of fluid in closed conduit in one dimensional basing on Couette flow, Hagen Poiseulle law and friction factors and two-dimensional Navier Stokes equation are explained. Flow potentiality and its resistance are also explained including minor frictional losses like due to sudden expansion, sudden contraction, losses due to pipe bends and obstructions are also taken up in Chapter 6. Chapter 7 explains the Boundary layers over flat plates and their equations based on
