Baume; France 1728-1804] liquor and nutrition processing. image Be. A scheme, expressed in levels, that measures the fspecific gravity of drinks, essentially in saccherimetry. Many such scales were used. All hire a hydrometer graduated such that, for a few consistent m (the modulus), if d is the studying in an answer of particular gravity s, then (d - dw)s = (s - l)m, the place dw is the studying selected for natural water, frequently 0. What has been labelled the 'old' Baume scale makes use of m = one hundred forty four, it appears in keeping with an interpretation of Baume's unique scale as having sixty six° Be for robust sulphuric acid at 15°C, with s = 1. 8427, therefore m = a hundred and forty four. 32.
