Viscosity Calculator

Temp (°C): (effective temperature range is -20 to 150 °C)
Deg API: (applicable to crude oils from 12 to 40 Deg API)
Viscosity (cSt):

Note: The above program does not account for the affects of sulfur‚ asphaltenes or vanadium on the apparent viscosity of the crude oil. The presence of these substances may increase or decrease the relative viscosity of the process fluid.
