Hydrostatic thrust bearing, central pocket, capillary restrictor — fixed reference geometry

Reference-geometry calculator (60mm bearing radius — fixed, matching the original) for a circular hydrostatic thrust bearing with a central pocket fed through a capillary restrictor. Vary pocket radius, film thickness, pressure and fluid properties.

The legacy "please login" demo lock froze the bearing radius R0 to this exact value. Per docs/phase6/OWNER-DECISIONS-BACKLOG.md K4, this fixed geometry is kept exactly as in the original and only the inputs that were already free under the lock are exposed. Generalizing it is a deliberate future decision for Anton, not made here.

FIXED GEOMETRY: bearing radius 60 mm — the original demo lock froze this value.

De berekening is een letterlijke overzetting van de originele client-side JavaScript van /calculators/c11_3.htm. Resultaten zijn geverifieerd gelijk aan het origineel via een geautomatiseerde golden-master-test. Geen enkele formule is opnieuw afgeleid of “verbeterd”.
