Cathodic Protection
Bare and coated area from total area and coating breakdown fraction.
App id: CUR-03. Reference version 1.1.
How to fill it
Fill the inputs. The tool shows the outputs.
On the tool screen, Calc is the working sheet. Presets stores values you reuse. Reference is the formula, assumptions, and provenance below.
Formula
Abare = Atotal × breakdown, Acoated = Atotal − AbareInputs
| Name | Unit |
|---|---|
| Total area | m2 |
| Coating breakdown | % |
Outputs
| Name | Unit |
|---|---|
| Bare area (hero result) | m2 |
| Coated area | m2 |
Diagnose
This tool does not attach diagnose observations.
Assumptions
- Breakdown is an explicit input (0–100%). Enter 1% breakdown for 99% coating efficiency.
- Result is geometric area only; current requirement is computed separately.
Provenance
- Geometric exposed-area relationship Abare = Atotal × breakdown fraction.
