The graph below shows the approximate range of viscosities for selected cane factory products. This data is adapted from work by EEA Rouillard and

Kinematic viscosity @ 100ºC calculator; Viscosity index: KV40 °C cSt (mm²/s) KV100 °C cSt (mm²/s) Calculate Clear Standard practice for calculating viscosity index from kinematic viscosity at 40 and 100°C. Calculator for viscosity index (VI) according to ASTM D2270 and ISO 2909. Modules to calculate the Viscosity Index or the oil viscosity at 100°C. When we know the viscosity of an oil at 40°C and 100°C we can calculate its viscosity index. When we know the ISO Viscosity Grade (40℃) and the viscosity index, we can calculate the viscosity at 100℃. Viscosity index calculator The viscosity of a fluid is its resistance to flow and is highly influenced by temperature. It decreases with rising temperature, i.e. the fluid becomes more liquid. Viscosity Index Calculation Our Viscosity Index Calculator is our new online calculation tool where, by entering the results of your sample's kinematic values at 40 °C and 100 °C, you can have the viscosity index value calculated in an instant.

## Calculation. The viscosity index can be calculated using the following formula:.

2 Feb 2016 (It also applies to fluids like engine and automatic transmission oils, gear lubricants, and power-steering fluids.) The greater the viscosity index (VI)  An Internet search on “viscosity index calculator” will direct you to several Web pages. You can use these calculators in a variety of ways. For instance, if you  In addition to calculation of kinematic viscosity and viscosity index, VISDISK: • Performs oil blending calculations using the W. A Wright Method and the Chart. Viscosity Index Process Analyzer VI-4 - Analyzers BARTEC BENKE Integral calculation of viscosity index; Unparalleled temperature stability of ± 0.02 K  Therefore, another Viscosity Index was proposed for oils in this range (ASTM D2270 Procedure B). In this calculation, the candidate oil is compared with an oil

### 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 An Internet search on “viscosity index calculator” will direct you to several Web pages. You can use these calculators in a variety of ways. For instance, if you know the viscosity of a lubricant at two different temperatures, you can use the calculator to give you an estimation of the VI.

### From performance-enhancing polymers, viscosity index improvers, and synthetic base fluids to advanced pour point depressants for engine oils, driveline and

15 Mar 2018 Modules to calculate the Viscosity Index or the oil viscosity at 100°C. When we know the viscosity of an oil at 40°C and 100°C we can calculate

## Our Viscosity Index Calculator is our new online calculation tool where, by entering the results of your sample's kinematic values at 40 °C and 100 °C, you can

In addition to calculation of kinematic viscosity and viscosity index, VISDISK: • Performs oil blending calculations using the W. A Wright Method and the Chart.

Calculate the viscosity using the viscosity index The calculator on this site is for informative purposes only and we make no claims as to the accuracy, completeness or fitness for any particular purpose of the results produced by our calculators. 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. The viscosity index can be calculated using the following formula: [ citation needed ] where U is the oil's kinematic viscosity at 40 °C (104 °F), and L and H are values based on the oil's kinematic viscosity at 100 °C (212 °F). Our Viscosity Index Calculator is our new online calculation tool where, by entering the results of your sample's kinematic values at 40 °C and 100 °C, you can have the viscosity index value calculated in an instant. First the viscosity at 100°C is calculated using the viscosity at 40°C and the Viscosity Index. Calculation according ISO 2909 / ASTM D2270-226. Then the viscosity at temperature T is calculated with Ubbelohde-Walther equation according ASTM-D341.
