The Fundamentals of Viscosity
The Fundamentals of Viscosity The most important single property of a lubricant is its viscosity. It is defined as a measure of a lubricant's resistance to flow. The viscosity of any fluid changes inversely with temperature. As temperature increases, viscosity decreases and as temperature decreases, viscosity increases. The most common way that viscosity is measured…Read more
