In order to better understand cavitation, this research focuses primarily on the design and manufacturing of cavitating demonstration apparatus that will aid in establishing cavitation's underlying causes and effects. To be clear, this project is purely experimental and is best suited to mild steel for the frame and a centrifugal pump with variable pressure settings, as well as tanks (both suction and discharge tanks) and pipes to transport the fluid through a vented tube (the venturitube itself). From a 0.5hp input and pump speeds of 2850rpm, 950rpm, etc. It was possible to illustrate the circumstances for cavitation in order to estimate the cavitation index by allowing water to flow through a text section (venturitube) and obtaining pressure measurements at both the intake and constriction. Under one, it has been observed that cavitation can be noticed (1). Increasing velocity at a constriction causes the pressure head to decrease in a similar manner, as can be seen from the experimental findings presented in tabular and graphical form.

Keywords : Cavitation, venturitube, cavitation index, pressure head.
