PREDICTION OF KINEMATIC VISCOSITY AT 38 degC can be done using:
log µ38 = 4.39371 - 1.94733 Kw + 0.12769 Kw*Kw + 3.2629 x 10-4 API2
- 1.18246 x 10-2 Kw API
+ (0.171617 Kw*Kw + 10.9943 API + 9.50663 x 10-2 API2 - 0.860218 Kw API)
/ (API + 50.3642 - 4.78231 Kw)
Wilson K factor an be calculated using following equation: Kw = (1.8 Tb)1/3 / SG
Kw - Wilson K factor
Tb - normal boiling point in K
SG - specific gravity at 15.5 degC
