The Cavitation Demonstration Unit offers a clear andeasy-to-understand display of cavitation. Students create clearly visiblecavitation in a Venturi and take measurements of flow and pressure. The causes and effects of cavitation are one of the mostimportant subjects in any course on fluid mechanics. In severe cases, cavitationwill damage machines and hydraulic systems. It alsoallows students to understand the Venturi by studying upstream and throatpressures. Studentsuse theory and practical experiments to learn how to predict the onset ofcavitation. They gain practical experience of using the continuity equation and Bernoulli's equation. They use these to calculate flow and pressure, differentmethods of creating cavitation and causes of error. The apparatus is aself-contained, mobile unit. Designers and engineers must beaware of cavitation when they create a new design or installation. Cavitation Demonstration Unit is a purpose-designed teaching unit which enables efficientand effective investigations into the causes and effects of cavitation. The frame includes a handy worktop for student paperwork. It consists of a robust frame which holds a watertank (or reservoir), an electric pump, a flow-control valve, a flow meter and aVenturi.
