Sentence examples for viscosity indices from inspiring English sources

Vegetable oils have a greater ability to lubricate and have higher viscosity indices.

Chemically modified vegetable oils exhibit better lubrication ability, viscosity indices, and superior anticorrosion properties, because of the improved affinity of vegetable oils to metal surfaces.

Viscosity indices of the lubricating oils (SN150 and SN500) blended with polymers at different concentration levels [ranging from 1% to 5% (w/w)] were calculated by measuring kinematic viscosity (KV) values at 313 and 373 K.

However, the solvatochromism and viscosity indices did correlate with the pentameric LCO optical ability to distinguish Aβ and tau deposits.

A non-dimensional viscosity index indicated an increase in relative viscosity for every 1% reclaimed asphalt binder.

Viscosity index indicates the variation of viscosity with temperature.

A high value (normally >90) of viscosity index is an indicator of good lubricating oil.

The results (Table 3) indicate that the viscosity index increases with an increasing number of substituents at the mid- and end-points, which leads to an overall increase in the molecular weights of the products, resulting from an increased number of ester functionalities.

The effect of alkyl chain length on the efficiency of the prepared additives as viscosity index improvers for lube oil is indicated at Fig. 7, which indicates that the efficiency increases with increasing the alkyl chain length of both alkylacrylate and α-olefins.

The less the viscosity is changed by temperature, the higher the viscosity index.

Since little change of viscosity with fluctuations in temperature is desirable to keep variations in friction at a minimum, fluids often are rated in terms of viscosity index.
