Description
Calculate supplied overflow-height minus water-height margin.
Aquaculture records distinguish gross harvest, tare, retained water, sample expansion, feed withdrawal and recorded live counts. Delivered feed differs from ingestion, and nominal mesh geometry differs from behavior under load. Local mass, depth and energy terms do not establish animal welfare, water quality or suitable stocking.
Calculate supplied overflow-height minus water-height margin.
When to use this tool
Use Aquaculture Tank Overflow Height Margin when you already have waterHeight, overflowHeight and need to calculate supplied overflow-height minus water-height margin.
How to use the tool and how it works
- Enter waterHeight, overflowHeight. Use the units and conventions below.
- Run the tool. Correct any format, range, or cross-field input error before interpreting the output.
- Read signedGap. Use the output convention below.
Return overflowHeight-waterHeight, retaining negative values.1
| Input field | Meaning and units | Accepted input |
|---|---|---|
| waterHeight | Water Height | Required. Finite number. |
| overflowHeight | Overflow Height | Required. Finite number. |
| Output field | Interpretation | Returned shape |
|---|---|---|
| signedGap | Signed Gap | Required. Finite number. |

}Limitations and assumptions
- Coordinates need a common datum and unit. This does not measure a tank, calculate dynamic overflow, size plumbing or establish safe freeboard.
- Inputs must satisfy both the field types and the cross-field conditions above. Invalid input causes an error; a successful false flag or documented placeholder is a different result.
- Numeric calculations use binary floating point unless exact decimal-integer arithmetic is explicitly stated. No hidden measurement tolerance or decimal rounding is added; nonfinite or out-of-contract results are rejected. Numeric signed-zero results are exported as zero.
Alternative or Complementary methods
Review original weighing, sample, feed, water and equipment records. Use the complete veterinary, biological and engineering assessment for real operation; local record checks do not determine appropriate management or safe handling.
