Viscosity index calculator

Viscosity index (VI) is an arbitrary measure for the change of viscosity with temperature. It is used to characterize lubricating oil in the automotive industry. Viscosity Index The viscosity of a fluid is its resistance to flow and is highly influenced by temperature. ISO 2909 / ASTM D2270-226, calculation, calculator. First the viscosity at 100° C is calculated using the viscosity at 40°C and the Viscosity Index. Calculation 

Standard practice for calculating viscosity index from kinematic viscosity at specific, free temperatures. Calculator for viscosity index (VI) according to ASTM D2270 and ISO 2909. If values are used other than 40°C and 100°C, ASTM D341 is applied before calculating the viscosity index. Gear Oil Viscosity Calculator. We often have gear boxes where the correct viscosity gear oil is not known either because it is a used box and came without the manual, or it is now being used in a different setup from its original design. Calculation of Viscosity Index The viscosity index of an oil is calculated from its viscosities at 40 and 100°C. The procedure for the calculation is given in ASTM Method D 2270-74 for Calculating Viscosity Index from Kinematic Viscosity at 40 and 100bC. Table 1 of the Method lists the basic viscosity values of Temperature - Viscosity Relation [latexpage] Viscosity is a measure of a lubricating oil's resistant to flow. It is well-known from Hydrodynamic Lubrication Theory that viscosity plays a central role in the lubrication regime encountered in the machine element - the higher is the viscosity, Water - Absolute or Dynamic Viscosity - Absolute or dynamic viscosity of water in centipoises for temperatures between 32 - 200 o F; Water - Dynamic and Kinematic Viscosity - Online calculator, figures and tables showing viscosity of water at temperatures ranging from 0 to 360 °C (32 to 675 °F) - Imperial and SI Units
