Bernoullis Theorem Complete with Collecting Tank

Product Code : LSK-TWL-10817

Bernoullis Theorem Complete with Collecting Tank (SKU LSK-TWL-10817), usually called a Bernoulli's theorem apparatus, verifies Bernoulli's equation by reading piezometer heads along a clear acrylic duct with convergent and divergent sections. Civil, mechanical and chemical engineering students use it in fluid mechanics practicals. Science Lab Supplies manufactures the apparatus at its Plot 448, HSIIDC Industrial Area factory in Saha, Ambala, India, and supplies it to colleges, polytechnics, tender contractors and distributors.

Specifications

The one-piece clear acrylic test section is tapped at several points and connected to piezometer tubes. A pump circulates water in a closed loop between the supply tank, test section and measuring tank, with stainless steel tanks and wetted parts on a compact, stand-alone painted structure.

Applications and Experiments for the Bernoulli's Theorem Apparatus

Students set a steady flow, time the rise in the measuring tank to find discharge, then read each piezometer. Velocity head at each section follows from the flow area, so the sum of pressure and velocity heads can be compared along the duct to verify Bernoulli's theorem.

• B.Tech/B.E. civil and mechanical engineering: fluid mechanics lab experiments on the energy equation.
• Chemical engineering fluid flow labs: pressure and velocity head in converging and diverging flow.
• Polytechnic diploma practicals: measuring discharge with a collecting tank and stopwatch.
• Showing where losses appear in the divergent part of the duct.

Standard Scope of Supply

The set includes the acrylic test section with piezometer tubes, supply tank, inlet water tank, measuring tank, circulation pump, stopwatch and the painted support structure. The laboratory provides the 220 V supply, a 1/2-inch BSP tap water connection and a drain; distilled water is optional.

Packing, MOQ and Lead Time

You can get a quotation for one apparatus or for a whole hydraulics lab. It sets out packing, delivery time and price for that quantity, and further fluid mechanics benches can be listed alongside for a single engineering lab equipment order.

As a registered exporter with an Importer-Exporter Code, Science Lab Supplies can ship to buyers in Qatar, Sri Lanka, Vietnam, Malaysia, Peru and Egypt. Enquire via the contact page or enquiry cart; see also the lab tender page.

Frequently Asked Questions

How is the flow rate measured?
With the measuring tank and the stopwatch supplied: the time taken to collect a known volume of water gives the discharge through the test section.

Does the apparatus need a continuous water supply?
No. The pump recirculates water in a closed loop. A 1/2-inch BSP tap connection is used for filling, and a drain is needed near the unit.

Is Science Lab Supplies the manufacturer or a trader?
Science Lab Supplies is the manufacturer. This apparatus is built at its own factory in Saha, Ambala, India, and quotations are issued directly from the factory.

What electrical supply does it need?
It runs on a 220 V AC single-phase supply and draws 0.5 kW, so a standard laboratory socket with earth connection is suitable.
