Idealized solids vs real fabricated tanks
Each mode is a mathematical primitive. Real tanks include nozzles, heads, support rings, and code-driven corrosion allowances that are outside this calculator.
Model assumptions
- Perfect geometry (right sections, uniform thickness not modeled as a separate shell).
- Horizontal/vertical cylinder modes use the stated fill height assumptions in the grid notes.
- Ellipsoid and frustum formulas follow standard solid geometry; numeric guardrails clamp degenerate inputs.
- No hydrostatic head structural check or seismic sloshing.
References & further reading
- Standard geometry references (CRC handbook / undergraduate solid-geometry treatments).
- API 650 / EN 14015 etc. for real storage tanks are outside this educational calculator’s scope.

Frequently asked questions
- Does listing handbooks or API 650 mean the tool is code-endorsed?
- No. Names are for traceability and scope only; they are not an endorsement by standards bodies and do not replace licensed engineering review.
- Can I use the volume for custody transfer?
- No. This is geometric estimation only.
- Why is centroid height shown?
- For teaching and quick statics estimates; verify against CAD for fabricated vessels.
- Is CAD export available?
- Not from this page; copy numeric results manually.

Numerical models run locally in your browser as implemented. For contract-critical work, cite primary standards and qualified review.
