When students go for interview in BARC, ISRO or other PSUs or IITs, majority of students will say “Sir, my favorite subject is Fluid mechanics” :). Yes, its true because its simple and if you study it you will surely understand it. One thing that people tend to forget is they keep on reading the theoretical part of FM and think they have completed it but when they give test series or solve last year papers FM is one subject in which you will perform poorly even when you think that you know and have understood FM. So its very essential that along with every topic you keep on seeing GATE question so that you get an idea what all things to study and which topics are very important.
Do I need to read a book?
For those who are preparing on there own book is quite essential. Since in the notes there are many topics which are not explicitly explained so in order to understand the concept its necessary to have a reference book. Please note that never ever use local author books which students use to pass university semester exams they will never help. Always follow standard textbooks.
Those who are in coaching institutes who don’t get much time to study from a book they may prefer not to but in case of important topics or confusions books are the best refuge.
Which book to refer?
Its always preferred to read book that you have already studied during your BTech. In case you didn’t read any ???? like most of the engineers.
Following is the book that i would recommend-
