TRAINING OBJECTIVES
• Venturi theorem demonstration of with a Venturi tube.
• Pressure loss calculation of in a Venturi tube.
• Flow determination with the utilization of the static volumetric system.
• Diaphragm calibration and utilization to determine the flow value.
• Identification and utilization practical applications of the Venturi effect:
– Utilization as a suction pump for liquids mixture; industrial applications, fertilizer and water mixture for irrigation etc.
– Mixture of water and air; hydro-massage.
– Use Venturi tube as a flow meter.
• Study of cavitation, by identifying the pressure, temperature and flow levels in which it is produced.
• Decreasing the pressure inside the tank to obtain cavitation phenomenon and observe new conditions.

VENTURY EFFECT, BERNOULLI AND CAVITATION
The objectives of these experiments are the study of the Venturi effect, from the conception of the Venturi theorem, to observation and practical uses.
The applicable uses are found in the industry, agriculture, leisure, etc.
Another objective to study is the cavitation phenomenon, it is also possible to change the pressure conditions in the inlet tank, and therefore, it is possible to study different flows and pressures.
