A new correlation for some transport properties of aqueous solutions, based on the data published by Sawada et al. [1], is proposed. The main objective of the new fit is to give a smooth transition to the properties of pure water to allow the use of the fit in the region of very dilute solutions. Additionally, the quality of the fit to the experimental data is improved compared to the original correlation. An extrapolation of the new correlation in the other direction, i.e., to higher mass fractions and temperatures, is smooth but does not fully capture the trend described by other experimental datasets. To this end, the correlation has to be refined further.

稀溴化锂水溶液特性数据的低温相关性

基于 Sawada 等人公布的数据，水溶液的某些传输特性的新相关性。[1]，提出。新拟合的主要目标是平滑过渡到纯水的特性，以允许在非常稀的溶液区域使用拟合。此外，与原始相关性相比，实验数据的拟合质量得到了提高。另一个方向的新相关性的外推，即更高的质量分数和温度，是平滑的，但不能完全捕捉其他实验数据集描述的趋势。为此，必须进一步完善相关性。
