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 is used in advanced fluid mechanics and hydraulic engineering labs at degree level. Science Lab Supplies manufactures the apparatus in Ambala, India, at Plot 448, HSIIDC Industrial Area, Saha, supplying universities, tender contractors and distributors directly.
Specifications
The test section is a 60 m coil of copper pipe fed from the laboratory water supply. A bypass valve at the inlet discharges to waste, and an adjustable valve downstream of the solenoid valve sets the mean pipe pressure before closure. A Bourdon gauge shows system pressure and serves to calibrate the transducer.

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.
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.
Science Lab Supplies, an Importer-Exporter Code holder, can ship to buyers in Kenya, Ghana, Ethiopia, Tanzania, Uganda and the UAE. To enquire, use the contact page or the enquiry cart; the lab tender page explains tender supply.
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 the pipe coiled?
Coiling 60 m of copper pipe gives a long pipe run in a compact space, which spreads the surge oscillations out in time so they can be measured clearly.
Is Science Lab Supplies the manufacturer or a trader?
The apparatus is manufactured by Science Lab Supplies itself at its Saha, Ambala factory in India, so buyers get quotations straight from the maker.
