Bernoulli Apparatus Manufacturer India | Scientico

The Bernoulli’s Theorem Apparatus is the cornerstone demonstration piece in any undergraduate Fluid Mechanics laboratory. It gives students a direct, tactile understanding of how pressure head, velocity head, and elevation head interconvert as an incompressible fluid moves through a conduit of varying cross-section. This subcategory hub lists the fluid-mechanics teaching equipment Scientico India manufactures at its Ambala works, with a detailed focus on the Bernoulli apparatus and the wider set of instruments a well-equipped hydraulics laboratory typically requires.

Equipment in this range

Scientico manufactures a broad Fluid Mechanics teaching range. Rather than quote invented model codes, the units below are described generically so procurement teams can match them against their own syllabus requirement:

  • Bernoulli’s theorem apparatus, a horizontally mounted transparent acrylic conduit with a converging-diverging profile, fitted with eleven piezometric tappings that let students read the static pressure head at each station and confirm the total-head equation.
  • Hydraulic bench, the service module that supplies a regulated water flow, houses the sump tank, the centrifugal pump, and a volumetric measuring tank with a sight gauge for gravimetric or volumetric discharge calibration.
  • Orifice and mouthpiece apparatus, a constant-head tank with interchangeable sharp-edged orifices and mouthpieces for determining coefficients of discharge, velocity, and contraction.
  • V-notch and rectangular notch apparatus, an open-channel section with a stilling arrangement and a hook-and-point gauge for measuring head over the notch.
  • Reynolds apparatus, a long glass tube fed from a constant-head tank with a dye injector for visualising laminar, transitional, and turbulent flow regimes.
  • Losses in pipes / pipe friction apparatus, a manifold of parallel pipes of different bores and fittings, tapped for manometric measurement of major and minor losses.
  • Impact of jet apparatus, a transparent test chamber with interchangeable flat, hemispherical, and inclined vanes for verifying the momentum equation.

Typical experiments demonstrated

The Bernoulli apparatus and its companion units support the standard fluid-mechanics experiment list found in most Indian and international engineering curricula:

  1. Verification of Bernoulli’s theorem. For steady, incompressible, inviscid flow along a streamline, the total head is conserved: P/ρg + V²/2g + z = constant. Students read the piezometric head at each tapping, compute the velocity head from continuity (V = Q/A) at that station, sum the two, and plot the total head against distance to observe the small, real-fluid decline attributable to viscous losses.
  2. Coefficient of discharge of an orifice. Using the constant-head tank and orifice, students apply Q = C_d · a · √(2gh), where a is the orifice area and h the head above the centreline, then determine C_d from the measured discharge.
  3. Discharge over a V-notch weir. The theoretical discharge is Q = (8/15) · C_d · tan(θ/2) · √(2g) · H^(5/2). Students vary the head H, measure discharge volumetrically, and back-calculate C_d.
  4. Reynolds number and flow regime. Re = ρVD/μ is computed for a range of flow rates while dye filament behaviour is observed, letting students identify the transitional band (roughly 2000-4000) for pipe flow.
  5. Friction factor in a circular pipe. Head loss is measured with a differential manometer and reduced with the Darcy-Weisbach equation h_f = f · (L/D) · (V²/2g), giving the Darcy friction factor f as a function of Re.
  6. Impact of a jet on vanes. Momentum flux F = ρQV(1 – cos θ) is compared with the measured reaction, verifying Newton’s second law applied to a control volume.

Key specifications you should ask for

When floating an enquiry or tender for a Bernoulli apparatus and its hydraulic bench, the following parameters should be nailed down in writing. The ranges shown are indicative of what teaching-grade equipment typically offers:

Parameter Typical range for teaching-grade units
Test-section material Cast acrylic conduit for full visibility of flow and manometer readings
Number of piezometric tappings 9 to 11 along the converging-diverging section
Test-section bore range Approximately 14 mm to 28 mm across the varying cross-section
Manometer bank Multi-tube water manometer, transparent scale, typically 300-500 mm range
Sump-tank capacity (bench) Around 100-160 L
Measuring-tank capacity Around 40 L with sight gauge
Pump Single-phase centrifugal, roughly 0.5 HP, discharge in the range of 40-80 lpm
Frame Powder-coated MS or stainless tubular frame with levelling feet
Power supply 230 V, 50 Hz single-phase (110 V, 60 Hz on request for export markets)

Applications & syllabus fit

This equipment set is specified across Fluid Mechanics and Hydraulic Machinery labs in BTech and BE programmes in Mechanical, Civil, Chemical, Aeronautical, and Agricultural Engineering. It is equally at home in diploma-level polytechnic labs and in ITI trade-training workshops covering plumbing and hydraulics. Overseas, the same units serve TVET colleges, university foundation-year workshops, and vocational training centres. The apparatus scale keeps operating pressures modest, so it is safe for supervised undergraduate use while still producing readings that align well with theory.

Standards & compliance

Scientico India operates under an ISO 9001:2015 quality management system covering the design, manufacture, and export of laboratory teaching equipment. Products supplied into the European Economic Area are prepared in line with the applicable CE conformity requirements for the relevant low-voltage and machinery scope, with the appropriate declarations issued at shipment. For instrumentation-grade calibration or accredited third-party testing, please indicate this at the enquiry stage so that the appropriate certificate route can be arranged. General engineering good practice references such as ISO 5167 (differential-pressure flow measurement) can be adopted as procedural guides for teaching experiments where required.

Ordering & delivery

Scientico India has been manufacturing laboratory teaching equipment from Ambala since 1993 and ships to over sixty countries. Enquiries can be quoted on either an FOB Mundra / FOB Nhava Sheva basis or on a door-delivered CIF basis to most seaports served by regular liner traffic. Typical lead time for a Bernoulli apparatus with its dedicated hydraulic bench is in the range of three to five weeks from confirmed order, subject to concurrent workload; packing is in seaworthy plywood cases with foam cushioning of the acrylic conduit and manometer bank. Freight, duties, and any port charges are quoted as estimates at the time of pro-forma invoicing and finalised on booking. Institutional buyers with GeM, tender, or consortium requirements are encouraged to share the specification schedule so that the quotation can be prepared in the exact clause-by-clause format required.

Frequently Asked Questions

What is the working principle of a Bernoulli's theorem apparatus?

It demonstrates conservation of total head along a streamline for steady, incompressible flow: P/ρg + V²/2g + z = constant. Piezometric tappings along a converging-diverging conduit let students verify the trade-off between pressure head and velocity head as the cross-section changes.

How many piezometric tappings are typically provided?

Teaching-grade units usually provide nine to eleven tappings along the varying cross-section, feeding a common multi-tube water manometer bank for simultaneous reading of all stations.

Does the Bernoulli apparatus need a separate hydraulic bench?

Yes. The apparatus itself is the test section only. A hydraulic bench supplies regulated flow from a sump tank via a centrifugal pump and includes the volumetric measuring tank used to calibrate discharge.

Is Scientico India a manufacturer or a trader?

Scientico India is a manufacturer and exporter based in Ambala, operating since 1993 with an ISO 9001:2015 quality management system, and has supplied laboratory equipment to more than sixty countries.

Can the apparatus be supplied for 110 V, 60 Hz export markets?

Yes. The pump on the accompanying hydraulic bench can be specified for 110 V, 60 Hz single-phase supply for North American, Caribbean, and other 60 Hz territories at the enquiry stage.

What is the typical lead time and shipping basis?

Indicative lead time is three to five weeks from confirmed order. Shipments are quoted FOB Mundra or Nhava Sheva, or on a door-delivered CIF basis where regular liner service is available, with freight and duties treated as estimates until booking.
