Description

It consists of a venturi tube in which throat occurs the phenomenon of cavitation due to the depression created in it by the acceleration of the flow (Venturi effect).

For a correct observation of the phenomenon, the methacrylate venturi has been constructed.

The equipment also has two pressure gauges with which we can measure the overpressures and depressions produced. A regulating valve is used to regulate the flow rate, which allows fine adjustment of the flow.

REMARKABLE ASPECTS

  • The equipment can be connected to the hydraulic bank and to the hydraulic group with flow meter.
  • Optimal visualization of the phenomenon under study, for the manufacture of the venturi tube in transparent material and

black background.

Learning Objectives
  • Demostration of Bernoulli´s Theorem along a Venturi tube.
  • Calculation of the pressure loss of a Venturi tube.
  • Calibration and use of the Venturi tube as a flow meter.
  • Cavitation study.
