Viscosity blending is perhaps the most common operation in lubricant manufacture. All blenders rely upon their viscosity-blending calculators, often used as a magic black-box giving the right blend composition [1,2].

Calculation of the viscosity of a mixture of oils knowing their viscosities at a given temperature Select the temperature in °C. Enter the viscosity in mm²/s at this temperature for the 1st base oil. Enter the viscosity in mm²/s at this temperature for the 2nd base oil. Enter the ratio by weight of 1st base oil .

M = 100 / (Cw/s) + [(100 - Cw) / L] m =density of slurry mixture, kg/m3. ... s = density of solid in mixture, kg/m3. ... L = density of liquid in mixture, kg/m3. ... m = L*[1 + 2.5* + 10.05*2 + 0.00273*exp( 44230.24. m = 100 / (Cw/s) + [(100 - Cw) / L] ... s = density of solid in mixture, kg/m3. ... L = density of liquid in mixture, kg/m3.

There are several formulas and equations to calculate viscosity, the most common of which is Viscosity = (2 x (ball density ? liquid density) x g x a^2) ÷ (9 x v), where g = acceleration due to gravity = 9.8 m/s^2, a = radius of ball bearing, and v = velocity of ball bearing through liquid.

Aggregate blending is the process of intermixing two or more fine or coarse aggregates to produce a combination with improved grading or other properties.

The first step is to calculate the Viscosity Blending Index (VBI) of each component of the liquid blend using the following equation: (1) VBN = 14.534 × ln[ln(v + 0.8)] + 10.975. where v is the viscosity in square millimeters per second (mm²/s) or centistokes (cSt) and ln is the natural logarithm (loge).

RVP is the vapour pressure at 100 °F of a product determined in a volume of air four times the liquid volume. RVP is not an additive property. Therefore, RVP blending indices are used. A commonly used RVP index is based on an empirical method developed by Chevron Oil Trading Company (1971)
