Quick Reference

The Italian physicist Giovanni Venturi (1746–1822) described the phenomenon of increased flow rate and reduced pressure when fluid or air flows through a constriction in a tube. This effect is observed when airways are constricted by disease such as asthma, when large blood vessels have a region of constriction, in mine shafts of varying size, and in many other situations.
