Web11 jan. 2024 · Hydrometer readings are obtained at convenient temperatures, reading of density being reduced to 15°C or 20°C. The aim of this experiment The objective of this exp. is to measure and study density and specific gravity of different liquids by using hydrometer., it will provide sufficient information about light and heavy crude oils. WebStep 1: Your Hydrometer. A hydrometer is a tool used for measuring density. Hydrometers used for brewing will tell you the specific gravity of a liquid - a ratio of the liquid's density to that of water. Something with a SG of less than 1 is less dense than water (and will float), and something with a SG of above 1 is more dense and will sink.
