Twaddell scale
http://dbpedia.org/resource/Twaddell_scale an entity of type: WikicatScales
L'escala Twaddell és una escala , la unitat de la qual és el grau Twaddell, emprada en la determinació de concentracions de dissolucions que tenen una densitat superior a la de l'aigua. Fou inventada pel constructor d'instruments científics de Glasgow a principis del segle xix. És definida per °Twaddell = (densitat -1) × 200, on la densitat és mesurada en g/cm³. L'escala Twaddell és relacionada amb l'escala Baumé (°Bé) per l'expressió: ºTwaddell = (200 + ºBé)/(145 - ºBé)

Das Grad Twaddle (Twaddell) (Einheitenzeichen: °Tw), benannt nach dem schottischen Erfinder (Twaddell), war eine vor allem in Großbritannien gebräuchliche Einheit für die relative Dichte von Flüssigkeiten, die schwerer als Wasser sind. Gelegentlich wird das Grad Twaddle noch in englischsprachigen Ländern in der Milchwirtschaft und Lederindustrie benutzt. Die Relative Dichte bei 60 °F (15,56 °C) berechnet sich: 1 °Tw = 0 °Bé = 1,25 °Bx = 5 °Q = 1,005

The Twaddell scale is a hydrometer scale for reporting the measured specific gravity of a liquid relative to water. On this scale, a specific gravity of 1.000 is reported as 0, and 2.000 reports as 200. Concentrated sulfuric acid with a specific gravity of 1.8 has a Twaddell scale measurement of 160 (as per the linear relationship between readings and sp. gravity). The Twaddell scale is only used for liquids with specific gravity greater than that of water. The scale was used in the British dye and bleach manufacturing industries. While the Baumé scale was adopted throughout England, the Twaddell scale was used in England and Scotland.

The scale is named after the scientific instrument manufacturer William Twaddell of Glasgow, who first developed hydrometers on this scale at the start of the 19th century.
