Venturimeter are used to measure the velocity of flow of fluids in a pipe. They consist of short length of pipe shaped like vena contracta, or the portion with the least cross- sectional area , which fits into a normal pipeline. The obstruction caused to the flow of liquid at the throat of the venturi produces a local pressure drop in the region that is …
