Cavitation Demonstrator

Technical Description

The term cavitation is used for the formation of vapour bubbles in flowing liquids as a result of a large partial vacuum. The benchtop unit contains a venturi tube made of transparent plastic. Cavitation is induced when the pressure at the smallest cross-section drops below the vapour pressure of the water. The pressures at the inlet, at the smallest point and at the outlet of the venturi tube are displayed using the dial manometers. The flow rate can be read on a rotameter. The inlet pressure can be preset using a pressure reducer.
A supply of water is required.

Learning Objectives / Experiments
