# Kinematic viscosity

> [HTML Version](kinematic_viscosity.html)

The kinematic viscosity has to be given for two temperatures: n40 at 40°C and n100 at 100°C. Optionally the viscosity can be defined for up to two additional temperatures to cover a wider temperature range. The actual viscosity at the given temperature will then be interpolated using these values.

If a single kinematic viscosity at operating temperature is given, it can just be entered in both inputs and therefore will be used in the calculation.

A high viscosity results in a larger lubricant film, but efficiency will be reduced if it is too large.
