[Chris] can measure the height of the hydrometer above the level of the liquid in his fermentation bucket. Both the temperature and specific gravity are logged to a Raspberry Pi, and after combing ...

specific gravity Specific gravity is to water what vapor density is to air. Specific gravity is the relationship of the weight of a liquid to water or another liquid (Figure 5.16).

The transmitter measures this hydrostatic head pressure and offers the resulting liquid level. To obtain an accurate reading, the measurement device has to be located at the lowest point one wants to ...

For example, the specific gravity of a urea solution of 2 gm. per 100 ml. is 1.0058, but that of a sodium chloride solution of 2 gm. per 100 ml. is 1.0146; to put it differently, an increase of ...

Scientific American is part of Springer Nature, which owns or has commercial relations with thousands of scientific publications (many of them can be found at www ...

Kopp first clearly recognised the necessity of comparing the liquids when under strictly analogous conditions. By dividing the specific gravity of a liquid taken at the temperature at which its ...
