چکیده مقاله:
Abstract: Pressure dependence of viscosity of the lubricants is essential for most industrial applications. In the present work, experimental viscosities of three polyalkylene glycol ether lubricants including PAG1 (23 ethylene oxide units), PAG2 (29 ethylene oxide units) and PAG3 (21 ethylene oxide units) were correlated using a linear relation with high accuracy. This simple and accurate linear equation provides reliable extrapolation of viscosity data for this class of lubricant. In addition, we have analysed the pressure–viscosity coefficient () for these fluids. This property decreases when the pressure increases for three lubricants. The following sequence have been found for this coefficient PAG3 > PAG2 > PAG1.
