Minimum Required Wall Thickness is expressed in m. No universal acceptance threshold is defined by this calculator.

Worked Example

Verified calculation

Given:

  • External Design Pressure = 101325
  • Shell Outer Diameter = 2
  • Allowable Compressive Stress = 138000000
  • Factor of Safety for Buckling = 3

Expected Result:

  • Minimum Required Wall Thickness = 0.00048976811594203

Engineering Interpretation:

Under the given input conditions, the calculated result is: Minimum Required Wall Thickness = 0.00048976811594203 m.

The actual numerical result is computed by the Runtime engine using the persisted tool definition. The values shown here come from automatically validated test cases.
