Description
Return suspended-solids capture under constant flow.
Aquaculture material budgets distinguish as-fed mass, dry mass, specific energy and nutrient fractions. Offered feed, recovered feed and estimated intake are different quantities. Arithmetic balances do not determine biological utilization, an appropriate diet, disease status or a safe feeding recommendation.
Return suspended-solids capture under constant flow.
When to use this tool
Use Recirculation Suspended Solids Capture Term when checking the stated aquaculture feed, material or composition basis.
How to use the tool and how it works
- Enter flow, inletConcentration, outletConcentration, duration, unitFactor. Use the units and conventions below.
- Run the tool. Correct any format, range, or cross-field input error before interpreting the output.
- Read capturedMass, removalFraction. Use the output convention below.
Return suspended-solids capture under constant flow. Require nonnegative flow/outlet concentration/duration, positive inlet concentration/unitFactor; capturedMass = flow*(inlet-outlet)*duration*factor, removalFraction = (inlet-outlet)/inlet.1
| Input field | Meaning and units | Accepted input |
|---|---|---|
| flow | Flow | Required. Finite number; minimum 0. |
| inletConcentration | Inlet Concentration | Required. Finite number; strictly above 0. |
| outletConcentration | Outlet Concentration | Required. Finite number; minimum 0. |
| duration | Elapsed duration in the common time unit specified above. | Required. Finite number; minimum 0. |
| unitFactor | Unit Factor | Required. Finite number; strictly above 0. |
| Output field | Interpretation | Returned shape |
|---|---|---|
| capturedMass | Flow*duration*(inlet-outlet)*unitFactor; may be negative when outlet concentration is higher. | Required. Finite number. |
| removalFraction | Removal Fraction | Required. Finite number. |

}Limitations and assumptions
- Negative removal is retained; sampling alignment, actual capture, treatment efficacy and safe water conditions are not established.
- 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
Use verified feed and animal records, representative measurements and qualified aquaculture/veterinary advice for actual nutrition, welfare or water-quality decisions.
