 Def. The specific gravity of a solid or liquid substance is the ratio of its density to that of water, or, in other words, it is the ratio of the weight of a given volume of the substance to that of an equal volume of water. The water is distilled, and...  Principles of Mechanics - Сторінка 206автори: Thomas Minchin Goodeve - 1891 - 374 стор.Повний перегляд - Докладніше про цю книгу
