Bernoulli's Theorem Demonstration (MODEL ME-FM-1274E-R)
The ARL’s 1274E accessory demonstrates the application of Bernoulli’s Theorem and circumstances where it does not apply.
- Venturi section machined from clear acrylic
- Seven static pressure tappings plus a total head measurement
- Flow control valve
- Manometer board with eight tubes
- Quick-release fitting for easy connection to Hydraulics Bench
- Educational software available as an option
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.
