Mariotte|ˈmærɪət|
Also erron. Marriotte.
The name of Edme Mariotte (c 1620–84), French physicist, used in the possessive and attrib. to designate apparatus he devised and a principle he enunciated: Mariotte('s) bottle or flask, a bottle with an outlet near the bottom and an adjustable glass tube passing through a cork in the neck, which if filled to above the bottom of the tube gives a flow of constant head equal to the height of the bottom of the tube above the outlet; Mariotte's law, Boyle's law (see law n.1 17 c (b)); Mariotte's tube, a U-tube having one arm short and sealed at the end and the other elongated and open to the air.
1845E. West tr. Peschel's Elem. Physics I. v. iii. 220 On the same principle Mariotte's flask acts. Ibid. iv. 228 In such a case it is more convenient..to use..a Mariotte's tube.., which being graduated according to Marriotte's [sic] law, will show the amount of pressure. 1898J. C. P. Aldous Elem. Course Physics 171 (heading) Boyle's (or Marriotte's [sic]) law. Ibid. 172 (heading) Boyle's (or Mariotte's) tube. 1930Dougall & Deans tr. P. P. Ewald's Physics Solids & Fluids v. 217 The experiment is conveniently carried out by using the so-called Mariotte's bottle. 1966McGraw-Hill Encycl. Sci. & Technol. II. 313/1 The phenomenon was discovered independently by Edme Mariotte about 1650 and is known in Europe as Mariotte's law. 1974Nature 26 Apr. 798/1 Continuous flow of fluid..was maintained relatively constant by means of gravity flow from a Mariotte flask. 1975Williams & Wilson Biologist's Guide to Princ. & Techniques Pract. Biochem. iii. 93 This can be overcome by the use of a Mariotte flask which will keep the operating pressure constant. |
