Venturi effect

Etymology: Giovanni B. Venturi, Italian physicist, 1746-1822
a modification of Bernoulli's principle, which states that the pressure of a gas is reduced just beyond an obstruction or restriction in the vessel through which the gas is flowing. The pressure drop can be nearly eliminated if dilation of the vessel does not exceed 15 degrees. The effect is a factor in the design of respiratory therapy equipment for mixing medical gases.
