Physical Properties of Bio-Based Oils, Fluids, and Greases
|
From United Bio Lube
Technically, the Viscosity of an oil is a measure of the oils resistance to Shear. Viscosity is more commonly known as resistance to flow. If a lubricating oil is considered as a series of fluid layers superimposed on each other, the viscosity of the oil is a measure of the resistance to flow between the individual layers. A high viscosity implies a high resistance to flow while a low viscosity indicates a low resistance to flow. Viscosity varies inversely with temperature. Viscosity is also affected by pressure; higher pressure causes the Viscosity to increase, and subsequently the Load-Carrying Capacity of the oil also increases. This property enables use of thin oils to lubricate heavy machinery. Products & Services
