Product Code : SCL-PLE-11568
Quick Answer: The Bernoulli Principle Apparatus passes air through an acrylic tube with a constricted nozzle and pressure measurement points, showing that pressure falls where the air moves faster.
Last updated: 18 October 2026
Key Features
- Transparent acrylic tubes for visible airflow.
- Constricted nozzle creates narrow and wide sections.
- Pressure measurement points and indicators along the tube.
- Links the principle to lift on aircraft wings and flow in pipes.
Technical Specifications
| Specification | Value |
|---|---|
| Components | Air flow tube, constricted nozzle, pressure measurement points |
| Construction | Acrylic tubes, airflow chambers, pressure indicators |
| Air supply | Manual or pump-assisted (pump or blower) |
| Level | Secondary to higher secondary |
How It Is Used
Set the apparatus on a stable bench, connect a pump or blower and let air flow through the tube. Students read the pressure at the wide and narrow sections and relate the difference to the change in air speed. Keep the airflow controlled and avoid overpressure.
Frequently Asked Questions
What does the Bernoulli Principle Apparatus show at the narrow section?
Air speeds up where the tube narrows, and the pressure reading there falls, showing that higher fluid speed goes with lower pressure.
