Viscosity Index Calculator Viscosity index calculator The viscosity of a fluid is its resistance to flow and is highly influenced by temperature. Viscosity Index Calculator Viscosity index calculator The viscosity of a fluid is its resistance to flow and is highly influenced by temperature.
Viscosity indexes which can be found on most product data sheets typically range from 90 to 160 but can exceed 400 and be as low as -60.
. To improve this Viscosity conversion Calculator please fill in questionnaire. Understanding VI is important to discern whether the lubricant in question meets the assets. The thicker a liquid is the more viscous you can call it.
It is mostly used to characterize the viscosity-temperature behavior of. These data is enough to. Extracted with permission from ASTM D2270-10 - Calculating Viscosity.

KV40 C cSt mm²s KV100 C cSt mm²s Viscosity index. You already know this but by a different name. The change in an oils viscosity due to a temperature change is called the viscosity index VI.
Any mineral oil is supplied with the specification of kinematic viscosity values at two different temperatures usually at 40C and at 100C or at 100F and at 210F. The viscosity index can also give. The viscosity index VI is an arbitrary unit-less measure of a fluids change in viscosity relative to temperature change.
Viscosity Index Calculator This calculator uses centiStokes cSt which are equivalent to mm2s. To determine the viscosity index of engine oils the kinematic viscosity is measured at 40C and 100C and these metrics are then compared to those of two reference oils. 141 The values stated in SI units are to be regarded as the standard.
Here is a simple calculator that can be used to calculate dynamic viscosity of an oil at operating temperature if the dynamic viscosities at 2 other temperatures are known. Standard practice for calculating viscosity index from kinematic viscosity at 40 and 100CCalculator for viscosity index VI according to ASTM D2270 and ISO 2909. It decreases with rising temperature ie.
Kinematic viscosity 40ºC calculator. The calculator can be a useful tool for predicting viscosity at a target temperature but keep in mind. If you have the viscosity in centiPoise divide the centiPoise value by the oils viscosity.
The viscosity at the target temperature is calculated when you click the calculate button. The measure of a fluids resistance to flow is called viscosity. Kinematic viscosity 100ºC calculator.
