Tank Family R01.

Research record

The detail behind
the study.

Source-linked work for this revision. Reported checks describe the stated model or test; physical qualification and applicability to the current retrofit remain separate.

The supplied PDF and its live geometry register establish the Revision C 2,000-gallon comparison envelope: 3102 × 2101 × 1850 mm. The separate 3002 × 2001 × 1400 mm liquid-accounting prism is not a modeled cavity. Both STEP files are reference solids, not parts to manufacture.

No dimensions are invented for the 1,500- and 3,000-gallon family targets. capacity-accounting.json calculates the exact result from the rounded published dimensions and preserves the distinction between a reserve and measured displacement.

The earlier wet-pilot access study cannot prove extraction through this tank. Actual roof/openings, riser depth, shell construction, partitions, equipment and mating transforms must be modeled before that claim. TG0–TG5 remain open.
