Brief Overview: Viscosity and its Grading
This lecture will illustrate the concept of viscosity and different viscosity classifications, with a particular focus on viscosity grades of engine oil and industrial oil. A brief mechanism about viscosity index improver will be explained. Viscosity comparison table gives approximate equivalence of values for a typical conventional fluid.
