F1-15-MKII Bernoulli’s Theorem Demonstration
This accessory illustrates those circumstances to which Bernoulli’s Theorem may be applied. Also, separately, why in other circumstances the theorem gives an inadequate description of the fluid behaviour.
Description
This accessory illustrates those circumstances to which Bernoulli’s Theorem may be applied. Also, separately, why in other circumstances the theorem gives an inadequate description of the fluid behavior.
The test section consists of a classical Venturi machined in clear acrylic.
A series of wall tappings enable measurement of the static pressure distribution along the converging and diverging duct. A total head tube is provided to traverse along the centre line of the test section. These tappings are connected to a manometer bank incorporating a manifold with an air bleed valve.
Pressurisation of the manometers is facilitated by a hand pump. The test section is arranged so that the characteristics of flow through both a converging and diverging section can be studied. Water is fed through a hose connector and is controlled by a flow regulator valve at the outlet of the test section.
The Venturi can be demonstrated as a means of flow measurement and the discharge coefficient can be determined.

Features & Benefits
This unit has been updated and now:
- The classical venturi profile has been enhanced to industry standard, leading to better accuracy and efficiency in demonstrating Bernoulli’s theorem. This improvement will affect the flow dynamics within the unit.
- More pressure tappings have been added, resulting in increased pressure drop resolution. This enhancement allows for a more detailed analysis of pressure variations within the system, offering a more comprehensive understanding of fluid dynamics.
- The manometer height has been increased. This modification suggests that the unit can now handle greater flowrates, potentially up to 20 L/min. This is crucial for experiments or demonstrations involving higher flow rates, providing versatility in the application of the unit.
These improvements collectively contribute to a more advanced and capable apparatus for demonstrating Bernoulli’s theorem, offering better insights into fluid dynamics and providing a more comprehensive educational experience.
