GATE 2026 Fluid Mechanics Syllabus - IIT Guwahati has released the GATE Fluid Mechanics syllabus 2026 on its official website, gate2026.iitg.ac.in. The GATE XE-B syllabus is provided here. 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. 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.
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. IIT Guwahati will conduct the GATE 2026 exam on February 7, 8, 14 and 15, 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. |

Hello,
Yes, you can change your category from General to OBC in the GATE application form. This can be done during the correction window, which typically opens after the last date for application submission.
You will need to pay a correction fee of Rs. 500. Please ensure you upload a valid OBC certificate as per the prescribed format and date mentioned by GATE.
To make the change, log in to the GOAPS portal, navigate to the "Change personal data" section, and update your category. Submit the changes and pay the required fee.
Remember to complete the correction before the deadline, as no changes will be accepted after the final date.
Hope it helps !
