Discovery of the venturi effect: Giovanni Battista Venturi

Giovanni Battista Venturi was an Italian physicist and discoverer of the Venturi effect. The Venturi effect is famously used in several modern applications. By eliminating air from the piping and vessels when mixing fluids and ingredients, this Venturi effect yields the same effect as in human arteries. Giovanni Battista Venturi was born in a small town around Reggio Emilia, Italy and became a pupil of Lazzaro Spallanzani and Bonaventura Corti.
Giovanni started by teaching logic at the university of Reggio Emilia and after a couple of years became a professor at the university of Modena where he taught geometry.
In later years, he held positions as a ducal mathematician, state engineer, and auditor between 1780 e 1796.
In 1796 he moved to Paris where he wrote his most important work “Experimental research on the topic of lateral fluid transmission”.
Today, Giovanni Battista Venturi is remembered for his significant contributions in the studies of fluid mechanics. Most notably, with the description of the Venturi effect, which studies the connection between the speed of a fluid and the subsequent pressures within a tube.
Inox-Fer applied this principle in the DR dissolving systems.

venturi effect principle

The Venturi effect states that in a situation with constant mechanical energy, the velocity of a fluid passing through a constricted area will increase and its static pressure will decrease.
For this reason, the Venturi effect is called a hydrodynamic paradox. Broadly speaking, the pressure increases in relation to the restriction of the area and the static pressure decreases as a direct consequence of Bernoulli’s equation.
Inox-Fer applied this principle in the DR dissolving systems.
