Applied Fluid Mechanics: Laboratory Investigation of Cavitation

This report presents results of the experimental measurements of the cavitation phenomena in a Venturitube with water and Theoretical and Practical pressure drop between Venturi inlet and throat. Pressure asvariants was measured at the inlet and throat. In every case, the throat diameter is equal to ۴.۵ mm. Theaverage flow rate ranges from ۸۷۰ to ۱۷۲۰ L/h. Flow rate, upstream and downstream pressure, and watertemperature were recorded during measurements. Additionally, theoretical pressure drop for different flowconditions was collected using the Bernoulli equation. Since numerical modeling of the cavitationphenomena in Venturi tubes is still very difficult and, in many cases, even quantitative agreement isimpossible to obtain, this experiment help provide more information about this type of flow.
