Ultra-low viscosity oils are becoming the norm for modern engines, especially smaller units prioritizing efficiency.

But there's more too it than that! We'll start by defining viscosity using Newton's Law of Viscosity, that describes the ...

If I then pour honey into the cup I will find that the cup drains very slowly. That is because honey's viscosity is large compared to other liquids' viscosities. If I fill the same cup with water, for ...

THE viscosity of liquids is a subject which, so far as I know, has hitherto been without any general theoretical basis. No physical mechanism, for example, has ever been brought forward to account ...

THE FireDos foam proportioners with high-viscosity foam concentrates were again subjected to FM tests – with convincing results: The optimised proportioning s ...
