Water Hammer Apparatus
Product Code : LSK-FM-10473
Water Hammer Apparatus (SKU LSK-FM-10473) demonstrates the pressure surge that travels along a pipe when flow is stopped suddenly. A solenoid valve closes the end of a long copper pipe coil while a pressure transducer captures the fluctuations. It suits advanced fluid mechanics and hydraulic engineering labs at degree level. Science Lab Supplies manufactures the apparatus at its Saha, Ambala, India factory (Plot 448, HSIIDC Industrial Area), with quotations going directly to universities, contractors and distributors.
Specifications
The 60 m water hammer rig is itemised in the table, one fact per row. In short, a coil of copper pipe is fed from the laboratory supply; a bypass valve at the inlet discharges to waste, an adjustable valve downstream of the solenoid valve sets the mean pressure, and a Bourdon gauge and transducer record the pressures.

Applications and Experiments for the Water Hammer Apparatus
Students set a steady flow and mean pressure, shut the solenoid valve and record the pressure rise and the oscillations that follow. From the results they estimate the pressure-wave speed and compare the surge with theory, a topic in unsteady-flow units of B.Tech/B.E. civil and mechanical engineering and M.Tech hydraulics.
- Measuring the pressure rise caused by sudden valve closure.
- Estimating pressure-wave speed from the period of the oscillations in the 60 m pipe.
- Effect of initial flow and mean pressure on surge magnitude.
- Calibrating the pressure transducer against the Bourdon gauge, whose tube mechanism can be seen through the transparent back of the Bourdon Gauge; gauges themselves can be checked on a Dead Weight Pressure Gauge Tester.
Closure produces sharp pressure surges, so tests should be run under supervision with all fittings secure.
Standard Scope of Supply
The apparatus consists of the 60 m copper pipe coil, the inlet bypass valve, the solenoid valve at the discharge end, the downstream adjustable valve, the electronic pressure transducer and the Bourdon pressure gauge. The laboratory provides the water supply to which the inlet connects.
Packing, MOQ and Lead Time
Price requests can be for one apparatus or a larger quantity, and the quotation lists packing, delivery time and price for that order. Related engineering lab equipment in India, such as pressure-measurement units, can be quoted with it on one document.
Science Lab Supplies, an Importer-Exporter Code holder, can ship to buyers in Kenya, Ghana, Ethiopia, Tanzania, Uganda and the UAE. Questions about the transducer readout can be raised on the contact page; the enquiry cart suits a straightforward quotation request, and the lab tender page deals with tenders.
Frequently Asked Questions
Does it need a hydraulic bench?
No. The inlet of the copper pipe connects to the laboratory water supply, and the bypass valve at the inlet end discharges excess water to waste.
How are the pressure surges recorded?
An electronic pressure transducer near the solenoid valve measures the fluctuations when the valve shuts. For the readout or recording arrangement you prefer, please ask through the contact page.
Why is such a long pipe used?
The copper pipe is 60 m long and arranged as a coil. A long pipe gives the pressure wave a longer journey between the valve and the inlet, so the period of the surge oscillations is long enough to record clearly.
Is Science Lab Supplies the manufacturer or a trader?
Science Lab Supplies produces the water hammer rig in its own Saha, Ambala works in India; you receive the quotation from that manufacturing team, not from a stockist reselling the apparatus.
