WebRelative density, or specific gravity, is the ratio of the density (mass of a unit volume) of a substance to the density of a given reference material. Specific gravity for liquids is nearly always measured with respect to water at its densest (at 4 °C or 39.2 °F); for gases, the reference is air at room temperature (20 °C or 68 °F). The term "relative density" (often … http://www.csgnetwork.com/specificgravliqtable.html
How to Use and Read a Hydrometer - Grainger KnowHow
WebNote: To use chart, choose specific gravity reading and temperature c’osest to the unknown sample and apply correction by moving the decimal point (3) places to the left. For … WebOct 3, 2014 · We use a hydrometer to measure specific gravity, in order to test the composition of fuel received from our suppliers. To determine the weight percent of methanol we use a chart provided by The Methanol Institute that correlated specific gravity to weight percent at different temperatures.
