Bernoulli's Theorem
Product Code : LSK-FM-10454
Bernoulli's Theorem apparatus (SKU LSK-FM-10454) is a horizontal Venturi tube with many pressure tappings to water manometers, so students can study the full pressure distribution along a convergent-divergent passage and compare it with Bernoulli's equation. It stands on the Digital Hydraulic Bench in engineering fluid mechanics labs. Science Lab Supplies is the manufacturer, building it at Plot 448 in the HSIIDC Industrial Area of Saha, Ambala, India, and dispatching it straight to colleges, polytechnics, tender contractors and distributors.
Specifications
The Venturi is typical of meters used in industry but carries far more tappings. A vertical manometer panel with a scale behind the tubes gives direct water-level readings, a common manifold with an air valve sets the datum, and a downstream valve controls flow without upstream turbulence. Plastics and corrosion-resistant finishes are used throughout.

Applications and Experiments for the Bernoulli's Theorem Apparatus
The apparatus demonstrates how pressure head changes with cross-section along a Venturi at steady flow, and lets students compare the ideal pressure distribution with the measured one. Because the bench measures the flow rate, they can also find the meter coefficients over a range of flows in fluid mechanics lab experiments.

Standard Scope of Supply
Each set includes the horizontal Venturi tube, the downstream flow-control valve, the manometer panel with tubes, scale and air-valve manifold, the base with adjustable feet, and a hand-pump for adjusting the manometer datum. The Digital Hydraulic Bench it stands on is a separate product.
Packing, MOQ and Lead Time

Frequently Asked Questions
Why is the flow-control valve downstream?
Placing the valve after the Venturi means it causes no upstream turbulence, so the pressure readings along the passage reflect the Venturi itself.
What results do students calculate?
They compare ideal and measured pressure distributions, and use the bench flow rate with the upstream and throat heads to calculate the coefficient of discharge of the meter.
Is Science Lab Supplies the manufacturer or a trader?
Manufacturer. The apparatus is fabricated in the company's own factory at Saha, Ambala, India, and the quotation comes from the maker rather than an agent.
How is the manometer datum adjusted?
Students connect the included hand-pump to the air valve on the manifold above the tubes and set the water levels to a convenient part of the scale.
