Sensitiveness of a Hy-drometer.— A Nicholsons hydrom-eter is to be loaded as in Fig. 4, byplacing weights in the upper pan,a, until a small ring round thelower part of the wire stem sinksjust beneath the surface of thewater; then small weights areadded, say 5 centigrams, until bythe sinking ofthe… … Fig. 4. ir 5.] PRECAUTIONS. 9 is estimated roughly by a small millimetre scale. Wenow calculate the effect of one centigram in sinkingthe instrument. This is called the sensitiveness(§ 41) of the hydrometer, and is useful in determin-ing the degree of precision with which the adjust-ments of the…
