To Demonstrate how Bernoulli's law applies to pressure
- Venturi Tube
Venturi Meter and Diagram.
The Venturi Flow-meter has a U tube manometer connected across two points of varying cross section. For horizontal fluid flow Bernoulli's equation states that the pressure is reduced where the cross sectional area is narrower. The pressure difference between these points is readily seen with even a modest flow of water. If required a Camera can be trained on the unit for a close up.
