Worked Example

Verified calculation

Given:

  • Maximum expected gas concentration (fraction of LEL) = 0.4
  • Minimum required purge time per standard = 60
  • Actual purge time = 360
  • Target residual concentration (fraction of LEL) = 0.002
  • Enclosure internal volume = 0.8

Expected Result:

  • Zone 1 area dilution volume = 960

Engineering Interpretation:

Under the given input conditions, the calculated result is: Zone 1 area dilution volume = 960 m³.

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.
