Worked Example
Verified calculation
Given:
- Basin Volume = 1200
- Influent Flow Rate = 0.015
Expected Result:
- Hydraulic Retention Time = 80000
Engineering Interpretation:
Under the given input conditions, the calculated result is: Hydraulic Retention Time = 80000 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.
