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)

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).

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

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.

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.

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 .

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].
