Venturi process
The Venturi process is a cheap method often used in technology for enriching liquids with gases or for mixing gases, liquids or solids. The medium intended for enrichment / mixing is introduced into the target substance via a venturi nozzle (a nozzle body, also known as a venturi tube , named after the physicist Giovanni Battista Venturi ). The process is much more economical compared to turbine processes , as there is only minimal pressure loss due to a specially shaped diffuser .
Applications in technology are diverse, such as B. Vinegar production (introduction of air), mixing of liquids, LPG, powders and other solids, etc.
The Venturi method in physics and aviation uses a Venturi tube to measure the flow velocity of liquids and gases. For example, the speed of an aircraft can be measured by suitable conversion.
