This is a literal lookup table, not a physics model — the "calculator" behind it is a piecewise if/else chain over the diameter selector, each branch just assigning fixed vendor spec-sheet numbers. No unit conversion is computed either: the metric and imperial columns are independently tabulated catalog values, not derived from each other. See newway-porous-bushing.ts for the companion bushing (sleeve) product line — different geometry (adds outer diameter and length), different fixed fly height (4 µm vs 5 µm here), and a different diameter range.

  • New Way Air Bearings — flat round porous-carbon air bearing catalog performance data (www.newwayairbearings.com).
  • All figures are published at a fixed 60 psi (0.41 MPa) supply pressure and 5 µm fly height — not adjustable, per the vendor data sheet and the original calculator’s own warning.

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