Viscosity “η” is one of the most important properties in Newtonian liquids (NLs). It depends on temperature, pressure, molar mass, etc. Its theoretical description is quite complex. For these reasons numerous empirical equations have been suggested, so far. Unfortunately, they have limitation of use. In this regard, firstly we model the relationship between the energy of Arrhenius ($E_a$) and the factor ($\mathit{ln}{A}_s$). Secondly, we deduce a simple empirical model that theoretically describes the viscosity (η). Besides that, we introduce two other interesting models: one relies $E_a$ and the Arrhenius temperature (T_A), by analogy, it looks like the phenomenon of charging a capacitor. The other estimates the boiling temperature “T_b” of an unknown NL. All these suggested models have been validated by using a data set of 157 pure solvents grouped from literature. These models will be useful for engineering data and science community. The model is reduced to a single variable without losing significant accuracy.

粘度“ η ”是牛顿液体（NLs）中最重要的特性之一。它取决于温度，压力，摩尔质量等。其理论描述非常复杂。由于这些原因，到目前为止已经提出了许多经验公式。不幸的是，它们具有使用限制。在这方面，首先我们对阿伦尼乌斯（${Ë}_{\mathrm{一种}}$）和因子（$\mathit{ln}{\mathrm{一种}}_s$）。其次，我们推导了一个简单的经验模型，该模型在理论上描述了粘度（η）。除此之外，我们还介绍了另外两种有趣的模型：一种依靠${Ë}_{\mathrm{一种}}$与Arrhenius温度（T _A）类似，看起来像是给电容器充电的现象。另一个估计未知NL的沸腾温度“ T _b ”。所有这些建议的模型均已使用文献中157种纯溶剂的数据集进行了验证。这些模型将对工程数据和科学界有用。该模型被简化为单个变量，而不会损失明显的准确性。
