VENTURI, Giovanni Battista (1746-1822). Recherches expérimentales sur le principe de la communication latérale du mouvement dans les fluides, appliqué à l'explication de différens phénomènes hydrauliques. Paris: Houel et Ducros, Théophile Barrois, 1797.
8° (210 x 130mm). 2 folding engraved plates by Picquet. Contemporary French mottled calf, covers with gilt roll-tool and fillet border, flat spine divided into panels by Greek key pattern, red morocco lettering-piece and repeated sunburst ornament, green edges (lightly rubbed).
FIRST EDITION. While professor of philosophy at Modena, Venturi was sent to Paris as secretary of a delegation representing the Duke of Modena. He remained for a year and a half, coming into contact with many learned French scientists, and publishing several treatises, one of which was this work describing the famous ‘Venturi effect,’ the reduction in fluid pressure which results when a fluid flows through a duct or restricted channel. Roberts and Trent call it a ‘classic and surprisingly rare work in experimental hydrodynamics, describing a series of experiments which the author undertook in Italy, using Poleni’s efflux apparatus.’ Bib. Mechanica pp.339-40.
