Fluid Mechanics Lab Equipment List: Apparatus Grouped by Topic
This fluid mechanics lab equipment list groups the usual apparatus by the topic it teaches. Use it to check a syllabus against what a lab already owns, or to draft the item list for a quote or tender. Each entry says what the apparatus shows and what to confirm before you buy.
Fluid mechanics studies how liquids and gases behave at rest and in motion. Lab work covers three angles: statics (fluids at rest), kinematics (how a flow moves), and dynamics (the forces and energy in a moving flow). The same ideas are used across many branches of engineering.
How to use this fluid mechanics lab equipment list
Start with the practicals in your course, then tick off the apparatus each one needs. Many units share a hydraulic bench, which supplies a measured flow of water from a sump tank. If you plan the bench first, several smaller accessories can run from it, which saves floor space and water.
The groups below follow the order most courses teach them in.
1. Fluid properties and hydrostatics
- Fluid statics apparatus and hydrostatic bench: pressure at depth, buoyancy, and Pascal's law.
- Hydrostatic pressure apparatus (centre of pressure): the force on a submerged plane surface and where it acts.
- Metacentric height apparatus: the stability of a floating body, as used in ship design.
- Viscometers: falling sphere or capillary tube types to measure viscosity.
- Dead weight pressure gauge tester: calibrating a pressure gauge against known weights.
2. Flow and pressure measurement
- Venturimeter and orifice meter test rig: finding the discharge coefficient of each meter.
- Rotameter: a flow meter with a float in a tapered tube, often fitted to the same rig.
- Pitot static tube apparatus: measuring local velocity from the difference between total and static pressure.
- Manometer bank: reading many pressure points at once; computer-linked versions log the readings.
3. Flow behaviour and energy
- Bernoulli's theorem apparatus: tappings along a tapered duct record static head, and a probe records total head, to test the energy equation.
- Osborne Reynolds apparatus: dye injected into a glass tube shows laminar, transitional, and turbulent flow.
- Impact of jet apparatus: a jet strikes flat, cup, and angled vanes, and students compare measured force with momentum theory.
4. Pipe flow, friction, and losses
- Pipe friction apparatus: manometers across a test length give the head loss, from which students find the Darcy friction factor.
- Energy losses in pipes and fittings: losses at bends, valves, sudden expansions, and contractions.
- Pipe network apparatus: how flow splits in series and parallel pipes.
- Water hammer and pipe surge apparatus: pressure waves caused by closing a valve quickly.
5. Open channel and groundwater flow
- Multi-purpose flume or glass-sided tilting flume: weirs, hydraulic jumps, and flow under sluice gates.
- Seepage and ground water flow apparatus: flow through soil, not an open channel. Used in civil and water courses.
6. Pumps, fans, and turbines
- Centrifugal pump test rig: head, flow, and efficiency curves at different speeds.
- Series and parallel pump unit: how two pumps combine.
- Cavitation demonstration unit: what happens when local pressure falls to vapour pressure.
- Pelton and Francis turbine test benches: impulse and reaction turbine performance.
- Gear pump, axial fan, and centrifugal fan units: positive displacement and rotodynamic machines compared.
- Hydraulic ram: lifting water with the momentum of a falling flow.
7. Flow visualisation and aerodynamics
- Hydraulic flow demonstrator: flow patterns around shapes made visible with dye or particles.
- Subsonic wind tunnel: lift, drag, and pressure around models in an air stream.
Quick reference table
This table sums up the fluid mechanics lab equipment list. It also shows which items need a bench.
| Topic | Core apparatus | Needs a hydraulic bench? |
|---|---|---|
| Hydrostatics | Centre of pressure, metacentric height | No |
| Flow measurement | Venturimeter and orifice meter rig | Often |
| Energy equation | Bernoulli's theorem apparatus | Usually |
| Flow regimes | Osborne Reynolds apparatus | Usually |
| Pipe losses | Pipe friction and fittings rigs | Depends on design |
| Machines | Pump and turbine test rigs | Most have their own sump |
The last column varies by design. So ask the supplier to state it for each item, so the lab does not end up with an accessory and no bench to run it.
Where this knowledge is used
Students who work through this list learn ideas that run through many industries. Examples include hydroelectric and thermal power plants, nuclear plant cooling circuits, hydraulic machines, heat engines, automobiles, water supply and building services, and refrigeration and air conditioning.
What to check before ordering
- Materials: stainless steel or plastic tanks and pipes resist rust; clear sections let students see the flow.
- Measuring ranges: flow, pressure, and speed ranges should match the experiment manual.
- Power supply: voltage, frequency, and phase for pumps and motors must match the destination country.
- Utilities: water supply, drainage, and floor loading for filled tanks.
- Manuals: an experiment manual with sample readings helps new staff run the practical.
For export orders, ask how pumps, gauges, and glass tubes will be packed, and check those parts first on arrival.
