It consists of a venturi tube in which throat occurs the phenomenon of cavitation due to the depression created in it by the acceleration of the flow (Venturi effect).
For a correct observation of the phenomenon, the methacrylate venturi has been constructed.
The equipment also has two pressure gauges with which we can measure the overpressures and depressions produced. A regulating valve is used to regulate the flow rate, which allows fine adjustment of the flow.
The equipment can be connected to the hydraulic bank and to the hydraulic group with flow meter.
