Worked Example
Verified calculation
Given:
- Actual Draft = 5.2
- Lower Draft Bound = 5
- Upper Draft Bound = 5.5
- LCB at Lower Draft = -0.85
- LCB at Upper Draft = -0.72
Expected Result:
- Longitudinal Center of Buoyancy (LCB) = -0.798
Engineering Interpretation:
Under the given input conditions, the calculated result is: Longitudinal Center of Buoyancy (LCB) = -0.798 m.
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.
