Certain kinds of motor oils behave differently. Ideally, an engineer would prefer the oil viscosity to remain the same when the engine is hot as when it is cold. Motor oil includes additives developed ...

The measurement of an oil’s resistance to flow is known as its viscosity. Usually, with a temperature increase, we can expect viscosity to diminish, and reduce with a temperature decrease. Temperature ...

Every fleet owner should know the basics about the viscosity of the lubricants they are using and why the viscosity matters. Fleets—especially mixed ones—require a variety of lubricants. This ranges ...

Fundamental constants: a minimum value of viscosity has been calculated by Kostya Trachenko and Vadim Brazhkin (Courtesy: iStock/3quarks). Viscosity is an everyday phenomenon recognizable in the ...

Our bodies are made up of countless cells, and each one is enclosed by a thin layer called the cell membrane. This membrane is not a rigid wall, but a soft, flexible sheet made of lipids. Beneath it ...

Sound waves can measure viscosity on the fly. Though viscosity is the degree to which a fluid resists flow, it is more specifically a measure of a fluid's molecular friction. It can be a useful ...

A recent study used various gas oils and blends with residual heavy oils in order to evaluate the predictability of four different correlations. The gas oils differed substantially in their ...

Students will experiment with three different liquids to determine the relative viscosity and flow rate of each liquid. Mount Nyiragongo is a volcano in the Democratic Republic of the Congo, 18 ...
