1/31/2024 0 Comments Viscosity index calculatorIf values are used other than 40C and 100C, ASTM D341 is applied before calculating. Fill in zero (0) in the weight percent column (Wt%) if Base oil #3 and-or Base oil #4 are not part of the mixing viscosities. Calculator for viscosity index (VI) according to ASTM D2270 and ISO 2909. You can use this calculator to predict mixing viscosities of 2-4 base oils. Viscosity temperature is not required but must be the same for all base oils viscosities. Fill in zero 0 (or leave default “0”) in Wt % if not included in the blending calculations. Please note: Leave the default value of “1” in the viscosity field if blending less than two liquids. If you don’t want to include 3rd and 4th base oils, fill any value (>1) in the viscosity cell and zero (0) in the Wt%.Ĥ- Repeat the same for Base Oil #4 by filling in the viscosity and Wt% of the Base oil.ĥ- Click Calculate to predict the mixing viscosity of the blend. Viscosity Calculator #3ġ- Fill the viscosity of Base oil #1 and weight percent (Wt%) in the third (Wt%) column.Ģ- Fill in the viscosity of Base Oil #2 and weight percent (Wt%) in the next column.ģ- Fill in the weight percent (Wt%) and Base oil #3 viscosity in the 3rd row. 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.Module #3: Mixing viscosities calculator to blend or mix more than two base fluids. Engineering), 34 years with Indian Oil Corporation Ltd. The use of any of the calculators' results is at the user's sole risk. ![]() The viscosity-temperature coefficient for oils. all three oils having the same viscosity at 210° F. Viscosity index calculation was performed with a computer program using kinematic viscosity at 40 C and 100 C. ![]() A high viscosity index ensures consistent lubricating properties across a. The higher the viscosity index, the lower the viscosity change of an oil at fluctuating temperatures. calculating the viscosity of gas mixtures. The viscosity of oils and base oils of lubricating greases from Klber Lubrication can be determined by means of the known kinematic viscosity at 40 C and 100 C. Out of this 23 years at HQ, contributing in framing petroleum QC policies at National level, with Oil Industry thru BIS, Civil and Defense Aviation- GOI, Ministry of Petroleum.Įxposer to Petroleum Product Quality Control thru Laboratory, Storage Location, Controlling Office working. The calculation of vis cosity index was originally based upon Saybolt units.4 Consequently if the accuracy obtainable with the Saybolt viscometer is insufficient, and this instrument is abandoned and replaced by another instrument of greater precision, viscosity index must be based either. Only the composition of the mixture and the molecular weights and viscosities of the pure components in the mixture are required. The momentum fraction of a mixture is calculated from the composition.
