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
Each specification of the Bernoulli apparatus and its collecting tank appears in the table below. In short, a one-piece clear acrylic test section with pressure tappings feeds piezometer tubes, and a pump circulates water in a closed loop through 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, followed by meter comparison on the Flow Meter Demonstration.
- Polytechnic diploma practicals: measuring discharge with a collecting tank and stopwatch.
- Showing where losses appear in the divergent part of the duct, then measuring pipe friction on the Friction Loss In A Pipe apparatus.
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.

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 needs a 220 V AC, single-phase electric supply rated at 0.5 kW. If your laboratory runs on a different voltage, mention it through the contact page so the quotation can confirm the electrical details.
