Lubricating oil
Thread Content
How does the viscosity of lubricating oil change when it contains impurities? ?
What impurities are there to look at? If it’s something like a diluent, the viscosity decreases. If it’s something like a thickener, the viscosity increases
Additionally, if mechanical and particulate impurities are present, the viscosity remains unchanged: lol
Lubricating oil must be free of solid impurities. It is generally used as lubricant for centrifugal pumps and compressors; as material flows into such systems, its viscosity usually decreases
There doesn’t seem to be a direct relationship between the two, right?
