Viscosity Index Mixture Solution

STEP 0: Pre-Calculation Summary

Formula Used

Viscosity Index = ((Aromatic's Viscosity-Lube Oil Viscosity)/(Aromatic's Viscosity-Paraffinic Viscosity))*100
VI = ((L-U)/(L-H))*100
This formula uses 4 Variables

Variables Used

Viscosity Index - Viscosity Index is defined as a measure of how much a fluid's viscosity changes with temperature.
Aromatic's Viscosity - (Measured in Centistokes) - Aromatic's Viscosity is defined as the measure of a fluid's resistance to flow.
Lube Oil Viscosity - (Measured in Centistokes) - Lube Oil Viscosity is defined as the measure of a resistance of one lube oil layer over another adjacent lube oil layer.
Paraffinic Viscosity - (Measured in Centistokes) - Paraffinic Viscosity is defined as the measure of internal friction between the layers of paraffinic fluid.

STEP 1: Convert Input(s) to Base Unit

Aromatic's Viscosity: 711.24 Centistokes --> 711.24 Centistokes No Conversion Required
Lube Oil Viscosity: 310 Centistokes --> 310 Centistokes No Conversion Required
Paraffinic Viscosity: 308.34 Centistokes --> 308.34 Centistokes No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

VI = ((L-U)/(L-H))*100 --> ((711.24-310)/(711.24-308.34))*100

Evaluating ... ...

VI = 99.5879870935716

STEP 3: Convert Result to Output's Unit

99.5879870935716 --> No Conversion Required

FINAL ANSWER

99.5879870935716 ≈ 99.58799 <-- Viscosity Index

What is Viscosity Index Mixture?

A viscosity index mixture is a blend of two or more oils with different viscosity indices. The viscosity index of a lubricant is a measure of how much its viscosity changes with temperature. A higher viscosity index indicates that the lubricant's viscosity will change less with temperature.

How to Calculate Viscosity Index Mixture?

Viscosity Index Mixture calculator uses Viscosity Index = ((Aromatic's Viscosity-Lube Oil Viscosity)/(Aromatic's Viscosity-Paraffinic Viscosity))*100 to calculate the Viscosity Index, Viscosity Index Mixture is defined as a measure of how much a fluid's viscosity changes with temperature. Viscosity Index is denoted by VI symbol.

How to calculate Viscosity Index Mixture using this online calculator? To use this online calculator for Viscosity Index Mixture, enter Aromatic's Viscosity (L), Lube Oil Viscosity (U) & Paraffinic Viscosity (H) and hit the calculate button. Here is how the Viscosity Index Mixture calculation can be explained with given input values -> 100 = ((711.24-0.00031)/(711.24-0.00030834))*100.
