CAVITATION PHENOMENON
The system for the demonstration of the cavitation phenomenon is a simple and practical equipment including a Venturi tube where the cavitation phenomenon occurs when we have the depression created by the flow acceleration (Venturi effect).
The system grants great observation of the studied phenomenon because Venturi tube is made in transparent material.
The equipment also includes a pressure gauge and a vacuum gauge to measure the generated overpressure and low pressure; a membrane valve is included for precise flow control adjustments.
For the full operating of this system, it is necessary to connect the item to the hydraulic bench or to a suitable hydraulic energy source.
