Hydraulics

Hydraulics and Fluid Mechanics for GATE Civil and ESE covers: fluid properties (viscosity, surface tension, compressibility), fluid statics (pressure, buoyancy, manometry), fluid kinematics (continuity equation, flow types), Bernoulli's theorem and applications, pipe flow (Darcy-Weisbach equation, Moody's diagram, pipe networks), open channel flow (Manning's equation, specific energy, hydraulic jump), flow over weirs and notches, and dimensional analysis (Buckingham Pi theorem).

These tests are ideal for undergraduate civil engineering students and candidates preparing for GATE Civil Engineering, ESE Prelims, SSC JE Civil, state PSC/PWD exams, and any other civil engineering competitive examination. All tests are completely free — no account needed.

Fluid Mechanics and Hydraulics (Water Resources Engineering) collectively carry approximately 8–12% weightage in GATE Civil Engineering, typically 8–12 marks out of 100. Open channel flow, pipe flow, and Bernoulli's theorem are the most tested topics. This subject includes both conceptual MCQs and Numerical Answer Type (NAT) questions.

In ESE Prelims Paper II (Civil Engineering), Fluid Mechanics and Hydraulics combined typically account for 15–20 questions, carrying 30–40 marks out of 300. Topics like fluid properties, Bernoulli's equation, pipe flow, open channel hydraulics, and hydraulic machinery (turbines and pumps) are all important for ESE.

Fluid Mechanics is the broader theoretical study of fluid behaviour (both liquids and gases) at rest and in motion, covering hydrostatics, kinematics, and dynamics. Hydraulics is a practical branch focused specifically on liquid (usually water) flow in pipes, open channels, and hydraulic structures. In GATE and ESE Civil Engineering, both are combined under Water Resources Engineering with emphasis on incompressible flow applications.
