Measurement method and influence factors of liquid viscosity

Abstract: Viscosity measurement is widely used in oil, chemical, textile, national defense, medicine and other industries. Measurement of SAP viscosity, and to study the relationship between different meteorological factors, for the construction of the sap flow model, understand the corrosion in the liquid flow tree preservation, provide a theoretical basis for revealing the stumpage anticorrosion mechanism. This paper summarizes the development of viscosity measurement methods, including the principles and characteristics of traditional capillary method, rotation method and vibration method, so as to provide some references for the development of liquid viscosity measurement methods.

1常见的液体粘度测量方法

粘度是指在流体中抗不可逆位置变化的能力,是对流体内部流动阻力的一种度量。人们对液体粘度的测量早已开始，并且发展了许多相当成熟的方法，如传统的毛细管法、旋转法及振动法等^[1]。
