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 duct, while 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 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.
