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.

Hope it will help you!!!

Hello dear candidate,

You will not receive another rectification mail unless and until there is still an error in your reuploaded signature. if everything is okay your status will change to accepted on the GATE portal.

My advice is that you should keep checking your application status on the official website of GATE 2026.

Thank you.

Hello,

Visit the below website to download the previous 15 years question paper of GATE exam.

You'll also get the solutions from it. These question papers will help you a lot in your preparation.

All the best.

This is likely a temporary portal or validation issue, not something you did wrong. When candidates try to change category from GEN to OBC-NCL during the GATE correction window, the system checks required fields and sometimes a supporting certificate or fee is needed. If any required data or document is missing, or the server is busy, the portal can show Something went wrong, please try again. Explain to them that first they should log into the GATE portal, open the Correction tab and confirm which fields are editable and whether a payment or document upload is required for category change. Tell them to clear browser cache or try a different browser/device and retry. If the error persists, advise contacting GATE support or the zonal office with a screenshot and timing of the error so officials can check server logs.

Hello,

The GATE 2026 Agricultural Engineering (AG) paper will have a total of 100 marks. Out of this, 15 marks are for General Aptitude and 85 marks are for core Agricultural Engineering subjects.

The marks are generally distributed among major topics like Engineering Mathematics (12–13 marks), Farm Machinery (10–11), Farm Power (14–15), Soil & Water Conservation (12–13), Irrigation & Drainage (10–12), Agricultural Process Engineering (10–12), and Dairy & Food Engineering (9–10 marks).

The official qualifying marks for GATE 2026 are not yet released. However, based on previous years, the cutoff for the Agricultural Engineering paper is expected to be around 25 marks for General, 22.5 for OBC/EWS, and 16.6 for SC/ST/PwD candidates.

Hope it helps !
