Basic concepts of fluid mechanics and hydraulic machinery are essential in all the engineering disciplines to get better understanding of the courses in the professional programs, and obviously its importance as a core subject need not be overemphasized.

Although at present several books by foreign authors exist in the subject of “fluid mechanics and hydraulic machinery ”, many students and Teachers alike have felt the need for a book on the subject particularly suited to the syllabi in FLUID MECHANICAND HYDRAULIC MACHINERY, for the degree course in Mechanical, Civil and other courses of engineering. Of Indian Universities. The present book is an attempt to fill the gap.

The authors have tried to develop the subject from the fundamentals and have given various practical applications of the important formulas. The numbers of problems have been solved to illustrate clearly the applications of the different theoretical results.

A book of this kind naturally draws from several sources of information and knowledge. We acknowledge our deep gratitude to many teachers, who have contributed to our knowledge of the subject directly or through their writings.

We have great pleasure in expressing our gratitude to eminent personality Mr. T Mr. Salman Ahmed “Chairman of ISL Engineering Hyderabad, for his help and encouragement towards growth of society in education.

The authors wish their readers a profitable and enjoyable journey through the text book. All comments and opinions suggesting any improvement in the book will be much appreciate
