Gas and Fluid Dynamics GD FD

It is a fringe topic in syllabus. It appears at end of textbooks of thermodynamics and is often poorly explained/covered. Book by Prof SM Yaha on Compressible flow is the best book for the topic. Unfortunately, the symbols he has used in the book are different from those used usually by everyone, which makes it painful to go thru the topic. So, I have decoded and made notes using usual symbols and covering those topics/derivations that are relevant to the exam.
GD notes

GD has only a handful of subtopics: derivations for convergent divergent nozzles, Rayleigh flow, Fanno flow, Normal shocks
But the difficult part is remembering the derivations and formulae for these topics
sub-topicwise solved GD questions

Fluid statics/dynamics is another topic which is ill treated by the exam. The subject as such is extensive which is clear if one sees the size of any textbook for the same(RK Bansal, Frank M White). So, it takes lot of time and returns are poor. So, I made notes in QnA form taking stuff from ESE questions.
