Air bearing, porous surface feed — fixed reference geometry
Reference-geometry calculator (Ø40mm outer diameter, 5µm film, β=0.6 — fixed) for an aerostatic thrust bearing fed through a porous surface (permeability-coefficient restriction).
Enkele labels op deze pagina zijn nog niet vertaald — de Engelse tekst wordt daar getoond.
The legacy "please login" demo lock froze D0/H0/B1. The film thickness is additionally hardcoded (5e-6) directly inside the mass-flow formula, so this is kept as a fixed-geometry reference calculator. Only the inputs that were already free under the lock are exposed.

- Aerostatic thrust bearing fed through a porous surface (permeability-based restriction).
- FIXED GEOMETRY: outer diameter 40 mm, film 5 µm, β=0.6 — the film thickness is also hardcoded directly in the mass-flow formula, not only via the demo lock.
- Generalizing the outer radius/film is a real model change and is not done here — see docs/locked-calculators-review.md.
De berekening is een letterlijke overzetting van de originele client-side JavaScript van /calculators/c12_4d.htm. Resultaten zijn geverifieerd gelijk aan het origineel via een geautomatiseerde golden-master-test. Geen enkele formule is opnieuw afgeleid of “verbeterd”.
