Worked Example

Verified calculation

Given:

  • Cryogen Mass = 25
  • Latent Heat of Vaporization = 199000
  • Total Heat Leak = 0.3

Expected Result:

  • Hold Time = 16583333.333333

Engineering Interpretation:

Under the given input conditions, the calculated result is: Hold Time = 16583333.333333 s.

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.
