Venturin.
/vɛnˈtjʊəri/, /vɛnˈtʃʊəri/, U.S. /vɛnˈt(ʃ)ʊ(ə)ri/ a. Used attributively to designate a short constriction in a tube between two longer tapered portions that are usually of unequal length but terminate with the same diameter, so that there is a drop in pressure in a fluid flowing through the constriction which may be used to determine the rate of flow or used as a source of suction; also devices having this form and the effect involved.
