The Uses of the Venturi Meter Sciencing

Mar 13, 2018 · A venturi meter is also called a venturi flowmeter. It is used to calculate the velocity of fluids in running through a pipeline. The fluid may be a liquid or a gas. The meter consists of a pipe with a narrowing throat that expands back to it''s original diameter on the other side of the choke point.

Venturi PrincipleHow do venturis work

A venturi creates a constriction within a pipe (classically an hourglass shape) that varies the flow characteristics of a fluid (either liquid or gas) travelling through the tube.

Mining the past and utilizing examples as diverse as Borromini''s churches and Frank Furness''s houses, Venturi addresses the complexity of architectural form, made visible through unexpected juxtapositions and scalar manipulations.
