Density of water by M. Tanaka
The density of water is very important due to its use in various fields of science and industry, including equipment calibration. This calculator is based on the method published by M. Tanaka in 2001, and is described for temperatures from (0 to 40) °C, the work was approved by the CIPM (International Committee of Weights and Measures) the relative standard uncertainty used for the formula is of the order of 1x10-5.
M. Tanaka's formula is modified to omit corrections for dissolved air and liquid compressibility, likewise the constant a5 is given for tap water, if another type of water is required the isotopic abundance must be calculated, this is the proportion or percentage in which the different isotopes of a chemical element are found in nature, in this case water, which can vary for different types of water, such as seawater, drinking water, distilled water, etc.
