Abstract
An Equation to predict the pressure viscosity of lubricants was derived. It is a characteristic that this new equation includes cohesive energy density (CED) as a parameter of pressure dependence of lubricant viscosity. CED is calculated with the viscosity, density and molecular weight that the measurement is easy. This new equation can be applied to mineral oils, synthetic (paraffinic / naphthenic / aromatic) hydrocarbon type fluids, ester type fluids and ether type fluids.
