Determination of the density of a liquid using an aræometer (Archimedes' principle)
beer, beer-based beverages, NAB, beverages, liquid
Determining the density by using the buoyancy of a hollow body of constant volume requires an aræometer (hydrometer) with a suitable measurement range. The buoyancy corresponds to the weight of the water displaced by the submerged hollow body and is directly proportional to the density of the displaced fluid.
Determination/calculation of the apparent extract content from the SGA20/20 or the density of a liquid
wort, beer, beer-based beverage, NAB, beverage
Determine the SGA20/20 obtained from pycnometry or the density measured with a precision hydrometer or another device for measuring the density. Using the value from the SGA20/20 measurement or the density from the sugar, alcohol, original gravity and correction table according to GOLDINER/KLEMANN, BLOCK, KÄMPF or a polynomial, determine the apparent extract content of the sample.
