The Relation Between The Mean Molecular Weight And The Absolute Viscosity Of Lubricating Oils, John Isler Moore Jan 1933

The Relation Between The Mean Molecular Weight And The Absolute Viscosity Of Lubricating Oils, John Isler Moore

Masters Theses

"Of all the properties required of a good lubricant the most important is that of the viscosity at the temperature of its use. Most lubricants consist of oils blended or compounded together in such a way as to produce an oil of a desired viscosity, falling in the special group of viscosities expressed by the Society of Automotive Engineers in their tabulations.

There have been several methods developed to enable the refiner to blend quickly and efficiently although Bell stated that the methods were largely that of trial and error. Herschel formed a chart for blending by the logarithmic rule …
