Bernoulli Tube Set Manufacturer,Supplier and Exporter in India
Product Code : EL-SLE-4795
Jlab Export is a leading Bernoulli Tube Set Manufacturer,and suppliers in India
Bernoulli Tube Set (code EL-SLE-4795) is a flow apparatus for showing the Bernoulli effect produced by water flowing through a tube, used in school and college physics labs. It has a straight tube 500 mm long with a 10 mm bore near its centre, short side tubes in each section, and glass manometer tubes 270 mm long with an 8 mm bore, joined by rubber tubes. It is made by Jain Laboratory Instruments Pvt Ltd (JLab) at its works in Ambala, India.

How Does It Compare with Other JLab Bernoulli Apparatus?
| Model | Flow section | Pressure readout |
|---|---|---|
| This set (EL-SLE-4795) | Straight 500 mm tube with a 10 mm bore near the centre | Separate glass manometer tubes on short side tubes, joined with rubber tubes |
| Bernoulli Tubes | Horizontal tube with a constriction | Three side arms for attaching glass tubes as simple manometers |
| Venturi Tube Glass with Manometers | Glass tube narrowing at the centre | Three built-in U-tube manometers |
| Bernoulli Tube Apparatus | Rectangular transparent flow section | For verifying Bernoulli’s theorem |
Choose this set when you want a long straight tube with detachable glass manometer tubes that students connect themselves. The venturi tube has its manometers built in, and the rectangular-section apparatus shows how the water speed changes as the channel section changes.
What Is the Bernoulli Tube Set Used For?
It demonstrates Bernoulli’s principle, taught in class 11 physics under the mechanical properties of fluids: in a steady flow, where the water moves faster its pressure is lower. Water entering the narrower bore near the centre must speed up to keep the same volume flowing each second, so the water column in the manometer tube at that section stands lower than the columns on either side. The same idea explains the venturi meter, the atomiser and the lift on an aircraft wing, so the set links a textbook equation to something students can see.
Feed a steady flow from a tap or a constant-head tank through rubber tubing, keep the tube horizontal and clamped, and run water until the air bubbles have cleared. Adjust the flow so that every column stays within its manometer tube, then read the heights at eye level. Drain and dry the set after use.
What to Specify When Ordering
- Quantity — the minimum order is 10 sets; many labs use one per practical group.
- Mounting — a stand or clamps are not listed; say how you will hold the tube and manometers so JLab can advise.
- Spares — extra glass manometer tubes and rubber tubing are useful for breakages.
Frequently Asked Questions
What does the Bernoulli tube set demonstrate?
The Bernoulli effect produced by water flow — where the water flows faster, through the narrower bore, the pressure shown by the manometer column is lower.
What are the tube dimensions?
The straight tube is 500 mm long with a 10 mm bore near its centre, and the glass manometer tubes are 270 mm long with an 8 mm bore. The listing does not give the bore at the ends of the main tube.
Are the manometer tubes included?
Yes. The set carries glass manometer tubes and rubber tubes for joining them to the short side tubes on each section.
How is it different from the venturi tube with manometers?
This set has a separate straight tube with detachable glass manometer tubes; the venturi tube listing has three U-tube manometers built into a glass tube that narrows at the centre.
What is needed for an export quotation?
The quantity, the destination country and port or city, the delivery terms you prefer (for example FOB or CIF), packing or labelling requirements, and any tender reference.
Who manufactures the Bernoulli Tube Set?
Jain Laboratory Instruments Pvt Ltd (JLab), at its works in Ambala, Haryana, India.
OEM Manufacturer
JLab is the trading name of Jain Laboratory Instruments Pvt Ltd, a physics and mechanics lab equipment manufacturer in India, incorporated in 2017 and based on Hargolal Road, Ambala, Haryana. The Bernoulli tube set is built at JLab’s own works rather than bought from a trader, so schools, colleges, dealers and importers buy it factory-direct, each set is inspected visually before dispatch, and repeat orders are handled by the maker. JLab exports worldwide and ships to every region — for example France in Western Europe, the UAE in the Middle East, Greece in Southern Europe, Niger in West Africa and Bulgaria in Eastern Europe. Tender buyers can find details on the JLab lab tenders page.
