Venturi Tube in Coimbatore

Venturi Tube in Coimbatore

The Venturi effect is the reduction in Fluied Pressure that results when a fluid flows through a constricted section (or choke) of a pipe. The Venturi effect is named after its discoverer.

The simplest apparatus is a tubular setup known as a Venturi tube or simply a Venturi (plural: "Venturis" or occasionally "Venturies"). Fluid flows through a length of pipe of varying diameter. To avoid undue aerodynamic a Venturi tube typically has an entry cone of 30 degrees and an exit cone of 5 degrees.

Venturi tubes are often used in processes where permanent pressure loss is not tolerable and where maximum accuracy is needed in case of highly viscous liquids.
