Basis olie mengsels

The "Temperature" select (K) is only ever compared against its reference value (4.1, i.e. 40°C) in the source — it does not otherwise participate in a formula here. There is no blending equation in this source to generalize. This module reproduces the gate exactly: change any input away from the reference case and the output is undefined (NaN), matching the original blanking the field.

• Kinematic viscosity of a blend of base oils, by weight percentage.
• The legacy client-side source contains no blending formula — only a login gate around one hardcoded result for one reference case. This port is faithful to that: it is not a general blending calculator.

De berekening is een letterlijke overzetting van de originele client-side JavaScript van /calculators/oil_mixture.htm. Resultaten zijn geverifieerd gelijk aan het origineel via een geautomatiseerde golden-master-test. Geen enkele formule is opnieuw afgeleid of “verbeterd”.
