CALCULATION OF QUALITY OILS

The presented program allows to calculate the predicted values ​​of the quality indicators of technical oils:
- viscosity of a mixture of two oils, determine the viscosity and the amount of one oil
   according to known data for the mixture and the second oil;
- viscosity index of technical oil in accordance with ISO 2909-81;
- determination of the alkaline number (TBN) of the engine oil when it is prepared in
   Depending on the quality of the additive and oil (basic or semi-finished product);
- "Elementary composition" of motor oil when it is prepared in dependence
    from qualitative indicators of additive and oil (basic or
    semi-finished product). Information on qualitative indicators can be taken from
    quality passports or determined by laboratory tests
- calculation of the viscosity of a mixture of basic mineral or other oils with
 viscosity modifiers (thickeners). The software module allows
  predict the viscosity of the finished oil at 100 and 40 gr. Celsius, after
  mixing a predetermined amount of base oil with a certain amount
 a viscosity modifier;
- determination of the oil density at 15 and 20 degrees Celsius according to the known
   density and temperature.
   The allowed density range is from 650 to 1200 kg / m3.
   The temperature range is -40 to 120 degrees Celsius.
