GATE 2026 Fluid Mechanics Syllabus - IIT Guwahati has pulished the GATE Fluid Mechanics syllabus 2026 on its official website, gate2026.iitg.ac.in. Candidates can also find the GATE XE-B syllabus in this article. Aspirants must cover all the topics mentioned in the syllabus to ensure high scores. The GATE syllabus helps candidates know what to study and what to skip. The GATE fluid mechanics paper is an optional subject in the GATE engineering sciences exam. Along with the syllabus, candidates must also be aware of the GATE 2026 Engineering Sciences exam pattern, as fluid mechanics is included under XE. The Fluid Mechanics syllabus for GATE 2026 comprises 9 chapters. Candidates can check the detailed topic-wise GATE 2026 fluid mechanics syllabus on this page.
IIT Guwahati will conduct the GATE 2026 exam on February 7, 8, 14 and 15, 2026. The authority will prepare the GATE question paper as per the GATE fluid mechanics syllabus 2026. Along with the syllabus, candidates must check the GATE exam pattern to understand the format of the exam. Candidates are advised to practice the GATE mock tests after completing the GATE 2026 fluid mechanics syllabus.
GATE Fluid Mechanics syllabus 2026
IIT Guwahati has released the GATE fluid mechanics syllabus online. The GATE 2026 fluid mechanics syllabus includes topics such as flow and fluid properties, differential analysis, internal flows, external flows and more. The GATE engineering mathematics section has a weightage of 15 marks.
Chapters | Topics |
---|---|
Flow and Fluid Properties | Fluid Properties: Density, viscosity, surface tension, relationship between stress and strain-rate for Newtonian fluids. Classification of Flows: Viscous versus inviscid flows, incompressible versus compressible flows, internal versus external flows, steady versus unsteady flows, laminar versus turbulent flows, 1-D, 2-D and 3-D flows, Newtonian versus non-Newtonian fluid flow. Hydrostatics: Buoyancy, manometry, forces on submerged bodies and its stability. |
Kinematics of Fluid Motion | Eulerian and Lagrangian descriptions of fluid motion. Concept of local, convective and material derivatives. Streamline, streakline, pathline and timeline. |
Integral Analysis for a Control Volume | Reynolds Transport Theorem (RTT) for conservation of mass, linear and angular momentum. |
Differential Analysis | Differential equations of mass and momentum for incompressible flows. Inviscid flows - Euler equations and viscous flows - Navier-Stokes equations. Concept of fluid rotation, vorticity, stream function and circulation. Exact solutions of Navier-Stokes equations for Couette flow and Poiseuille flow, thin film flow |
Dimensional Analysis | Concept of geometric, kinematic and dynamic similarity. Buckingham Pi theorem and its applications. Non-dimensional parameters and their physical significance - Reynolds number, Froude number and Mach number. |
Internal Flows | Fully developed pipe flow. Empirical relations for laminar and turbulent flows: friction factor, Darcy-Weisbach relation and Moody’s chart. Major and minor losses. |
Bernoulli’s Equation and its Applications, Potential Flows | Bernoulli’s Equation: Assumptions and applications. Flow measurements - Venturi meter, Pitot-static tube and orifice meter. Elementary Potential Flows: Velocity potential function. Uniform flow, source, sink and vortex, and their superposition for flow past simple geometries. |
External Flows | Prandtl Boundary Layer Equations: Concept and assumptions. Boundary Layer Characteristics: Boundary layer thickness, displacement thickness and momentum thickness. Qualitative idea of boundary layer separation, streamlined and bluff bodies, and drag and lift forces. |

On Question asked by student community
Hello,
No,For Mtech you are not eligible to give GATE examination in 2nd year diploma and after completing your diploma degree
Only bachelor's degree holders can give GATE examination
Thank you
Hello
If you're in 2nd year right now, you can’t register for GATE 2026 just yet.
The exam is only open to students in the 3rd year or beyond in their degree.
It’s mainly because the GATE tests subjects that are usually taught later in your course.
But don’t worry, you are in a great position to start preparing early!
Focus on your basics, practice problem-solving, and build strong concepts now.
By the time you reach 3rd year, you’ll be well ahead of the game.
Hello,
If your GATE 2026 application shows "under scrutiny," continue to monitor your applicant portal and registered email for updates, as this is a routine process where officials verify your details. An "under scrutiny" status does not mean your application is rejected; you may be notified of discrepancies and given a chance to correct them during the application correction window, which opens later. Keep your application details accurate and prepare for the exam while waiting for the correction window to open.
I hope it will clear your query!!
Hello,
In the GATE application form , you should enter your name exactly as it appears in your official ID proof , even if the order is different.
For example:
If your ID proof shows Surname + First Name , enter it in the same way in the form.
Do not change the order to First Name + Surname.
This is important because your GATE admit card and scorecard will match your ID proof.
Keep it exactly the same to avoid any issues later.
Hope it helps !
Hello,
Yes, you as a Bachelor of Science graduate in home science can appear for the GATE 2026 exam, as the eligibility criteria include graduates from "Science" and other fields, as well as those in the 3rd year or higher of an undergraduate program.
I hope it will clear your query!!
