The Venturi effect is a special case of the Bernoulli effect, in the case of fluid or air flow through a tube or pipe with a constriction in in it. The fluid must speed up in the restriction, reducing its pressure and producing a partial vacuum via the Bernoulli Effect. The Bernoulli Effect is what gives lift to an airplane wing.
