Bernoulli Equation Verification Apparatus

The Bernoulli Equation Verification Apparatus is a fluid mechanics laboratory setup used for measuring changes in pressure head and velocity head as water flows through a passage of varying cross-section. It is intended for engineering and technical education laboratories, helping students verify conservation of mechanical energy under controlled flow conditions.

Product Description

The STEMAids Bernoulli Equation Verification Apparatus supports quantitative study of Bernoulli’s equation. Students measure pressure at selected points, determine flow velocity from discharge and cross-sectional area, and compare the calculated total head along the test section. The experiment links pressure energy, kinetic energy and elevation energy in flowing water.

A dependable Bernoulli experiment requires a level test section, stable flow, clear pressure readings and leak-resistant connections. The exact construction material, number of pressure taps, measuring range and hydraulic supply arrangement require confirmation from the approved STEMAids datasheet.

Key Features

• Direct energy-head comparison: Enables calculation of pressure head, velocity head and total head at multiple flow positions.
• Variable-area flow study: Demonstrates how velocity increases and static pressure decreases as the flow passage narrows.
• Visible pressure readings: Uses connected piezometer or manometer points to indicate local static-pressure head — [confirm configuration].
• Quantitative experiment: Supports discharge, velocity and total-energy calculations rather than observation alone.
• Repeatable operating conditions: Allows readings to be compared at different controlled flow rates.
• Engineering laboratory value: Connects continuity, conservation of energy and practical measurement uncertainty.
• Transparent accuracy limits: Accounts for friction, turbulence, trapped air, reading error and minor hydraulic losses.

How to Use the Bernoulli Equation Verification Apparatus

1. Place the apparatus on a stable surface and level the test section.
2. Connect the water supply and return lines according to the operating manual.
3. Start the flow slowly and remove trapped air from all pressure tubes.
4. Adjust the control valve until a steady flow condition is established.
5. Record the water level at every pressure-measurement point.
6. Measure discharge by collecting a known volume over a measured time.
7. Calculate velocity from discharge divided by the local cross-sectional area.
8. Calculate and compare pressure head, velocity head, elevation head and total head.
9. Repeat the procedure at additional flow rates.

Safety and handling: Keep electrical equipment and connections dry. Do not operate a pump without water, exceed the specified pressure or tighten transparent components excessively. Clean spills immediately.

Care & Maintenance

• Drain the system after use and flush it with clean water.
• Remove air bubbles and sediment from pressure tubes before each experiment.
• Inspect hoses, seals, valves and fittings regularly for leakage.

Frequently Asked Questions

What is a Bernoulli Equation Verification Apparatus used for?

It is used to compare pressure, velocity and elevation heads at different points in a flowing fluid and evaluate whether their total remains approximately constant.

What equation does the apparatus verify?

For ideal steady, incompressible flow along a streamline, the sum p/ρg + v²/2g + z remains constant.

Why does pressure fall in the narrow section?

For a constant incompressible flow rate, velocity increases where the cross-sectional area decreases. Under Bernoulli’s assumptions, the increase in velocity head corresponds to a reduction in static-pressure head.

Does the measured total head remain exactly constant?

Usually not. Real measurements include friction, turbulence, minor losses, air bubbles and instrument-reading uncertainty.

Is a hydraulic bench included with the apparatus?

The supplied hydraulic system was not verified. Confirm whether the quotation includes a pump, sump, measuring tank or connection to an existing hydraulic bench.

Who can use this Bernoulli experiment setup?

It is suitable for supervised civil, mechanical and related engineering laboratory courses at polytechnic, undergraduate and technical-training levels.
