چکیده مقاله:
Abstract: Temperature dependence of dynamic 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 the high accuracy. In addition, we have analysed the temperature–viscosity coefficient () for these fluids. This property decreases when the temperature increases and increases with the pressure from 0.1 to 60 MPa for three lubricants. The following sequence have been found for this coefficient PAG3 > PAG2 > PAG1.
