Specifically, the venturi effect is also referred to as a venturi effect. This phenomenon is named by its finder, italian physicist venturi. This effect is manifested in the phenomenon that the flow rate of the fluid increases when the restricted flow passes through a reduced flow cross section, the flow rate being inversely proportional to the flow cross section. While it is known from bernoulli's law that an increase in flow velocity is accompanied by a decrease in fluid pressure, a common venturi phenomenon. Colloquially, this effect is the creation of low pressure in the vicinity of a high velocity flowing fluid, thereby creating an adsorption effect.
