Chain: Drag

The line type wizard sets up the drag coefficients and drag diameters for a chain following the guidance of DNV OS E301, section 701.

DNV OS E301 recommends a normal drag coefficient of 2.4 (studless) or 2.6 (studlink). The normal drag diameter is $d$, where $d$ is the bar diameter. For the axial drag coefficient the recommended coefficients are 1.15 (studless) or 1.4 (studlink), and a corresponding axial drag diameter of $d/\pi$.
