The case
A 30 m atmospheric tank takes 157 MPa of tension at the bottom course and folds under 11 mbar of vacuum: 11 cm of water column. Thin plate resists when it is pushed outward, not when it is sucked inward. Generic case: Ø 30 m × 12 m cone-roof tank, steamed out at 100 °C with the valve under the vent closed.
