DESIGN CONSTRAINT: cell geometry must use GENERALLY-AVAILABLE stock tube; lengths/diameters flexible (baseline 1/2" + 3/4" 304 SS x 3.00")
The binding constraint is general off-the-shelf availability of 304 SS tube, NOT one fixed dimension set. Baseline/reference geometry stays 1/2" OD inner + 3/4" OD outer, ~1/16" (0.0625") water gap, 3.00" active length. Lengths AND diameters MAY vary as long as they are common stock sizes (standard SS tube ODs 1/2, 5/8, 3/4, 7/8, 1"; common cut lengths). For any chosen stock geometry, recompute C, water R, and resonance before building. Prefer scaling output by paralleling identical cells over inventing non-stock diameters. Per Chris Bake directive 2026-07-04 loosening the earlier hard lock to a single size.
