Worked Example
default_test
Given:
- c0 = 21
- v_line = 0.25
- q_purge = 2
- c_target = 100
Expected Result:
- minimum_purge_duration = 57.372694677836
Engineering Interpretation:
Under the given input conditions, the calculated result is: minimum_purge_duration = 57.372694677836 s.
The actual numerical result is computed by the Runtime engine using the persisted tool definition. The values shown here come from deterministically validated test cases.
Formula / Method
minimum_purge_duration = (v_line/q_purge)*60*log(c0*pow(10,4)/c_target)minimum_purge_duration.
