  • Wear volume approached as V = d·L·D, valid when the wear depth is large compared to the radial clearance.

The computation is a literal port of the original client-side JavaScript from /engineering-abc/calculators/c1_8.htm. Results are verified equal to the original by an automated golden-master test. No formula has been re-derived or “improved”.
