Venturi Principle|How do venturis work

The Venturi Principle 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 As the fluid velocity in the throat is increased there is a consequential drop in pressure Italian scientist Giovanni B Venturi (1746-1822).
