Viscosity Synonyms | Merriam-Webster Thesaurus

The main requirements for an engine oil are defined temperature-viscosity properties, protection against wear and corrosion, keeping the engine clean, holding particles like soot or abrasives in suspension, yield strength under compression and many more. Viscometers are used to measure the viscosity of a fluid under defined flow conditions. The different types of viscometry instruments have either the fluid stationary and let the object pass through the fluid or vice-versa. Hence, these instruments measure the drag caused by the interaction between the fluid and the object surface. The coefficient of viscosity of water at 10 o C is 1.3 x 10-3 N s m-2. Since F = ŋA x velocity gradient, the frictional force on an area of 10cm 2 in water at 10 o C between two layers of water 0.1 cm apart which move with a relative velocity of 2 cm s -1 is found as follows: For example, viscosity in ARA dropped 30cst by March to 100cst and there was a bigger decrease in Singapore, from 170cst down to 90cst, with an even bigger reduction in Malta, from 150cst to 50cst.

Viscosity may be an appropriate characteristic for solids in a plastic regime. The situation becomes somewhat confused as the term viscosity is sometimes used for solid materials, for example Maxwell materials, to describe the relationship between stress and the rate of change of strain, rather than rate of shear.

Viscosity is a measure of a fluid's resistance to flow. It describes the internal friction of a moving fluid. A fluidwith large viscosity resists motion because its molecular makeup gives it a lot of internal friction. A fluid with low viscosity flows easily because its molecular makeup results in very little friction when it …

VISCOSITY | meaning in the Cambridge English Dictionary

What Is Viscosity? - Precision Cleaners Chemists have a slightly different feel for the phenomenon; viscosity is defined as its resistance to gradual deformation. This corresponds to the informal concept of “thickness” — for example, honey is thicker and has a much higher viscosity than water. According to Wikipedia, viscosity is the friction between the molecules of fluid. Viscosity - Glenn Research Center Jun 12, 2014 Viscosity - Dynamic Converter
