THE CURRENT NEED OF BIOTECHNOLOGY STUDENTS AS WELL AS FACULTIES AND UNAVAILABILITY OF COURSE SPECIFIC BOOKS IN THE MARKET ENCOURAGED US TO WRITE THE BOOK OF FLUID MECHANICS FOR BIOTECHNOLOGY. THE BOOK HAS BEEN PREPARED KEEPING IN MIND THE AKTU SYLLABUS FOR BIOTECHNOLOGY STUDENTS BUT IT WILL PROVE TO BE FRUITFUL FOR OTHER BRANCHES AND UNIVERSITIES AS WELL The first unit of the book contains fluid introduction, properties, Bernoulli’s equations and their applications. In further units the fluid mechanics has been developed in a lucid and easy to understand manner. Students will find a complete coverage of the syllabus along with sufficient theoretical and numerical examples. At the end of every chapter unsolved questions have been incorporated for practice. Reference books have also been suggested so that students may consult for much detailed study for research purposes. This is first book on the fluid mechanics for biotechnology and we have tried our best to avoid any error or mistakes, nevertheless, readers are welcome to suggest any improvement or corrections so as to make the book better day by day. We hope that students as well as faculty will find the book to useful in regular teaching and consulting for specific topic.
