ESE 2021 – Fluid Mechanics (FM) IES Official Syllabus
Fluid Mechanics: Basic Concepts and Properties of Fluids, Manometry, Fluid Statics, Buoyancy, Equations of Motion, Bernoulli’s equation and applications, Viscous flow of incompressible fluids, Laminar and Turbulent flows, Flow through pipes and head losses in pipes.
The above syllabus is just a outline given by UPSC to mechanical engineering students. From the above syllabus students may feel the syllabus is very short, but when they start there preparation they come to know that this syllabus is just the heading of chapters they are reading and it become very difficult to students to decide which topic to read and which topic to leave. So we are giving expert advice, following topics will need to be covered by students while preparing for ESE i.e engineering services exam.
