Description
Update a supplied cumulative exchange fraction.
Tank geometry, exchange and equipment budgets use explicit volume, flow, mixing and efficiency assumptions. Ideal complete mixing differs from replacing distinct water portions, and energy usage differs from power. Nominal calculations do not establish actual oxygenation, animal welfare or safe installation.
Update a supplied cumulative exchange fraction.
When to use this tool
Use Water Exchange Increment when checking the stated aquaculture geometry, exchange or equipment term.
How to use the tool and how it works
- Enter currentFraction, exchangedFractionOfRemainder. Use the units and conventions below.
- Run the tool. Correct any format, range, or cross-field input error before interpreting the output.
- Read newFraction, increment. Use the output convention below.
Update a supplied cumulative exchange fraction. Require both fractions in [0,1]; increment = (1-current)*exchangedFractionOfRemainder, newFraction = current+increment.1
| Input field | Meaning and units | Accepted input |
|---|---|---|
| currentFraction | Current Fraction | Required. Finite number; minimum 0; maximum 1. |
| exchangedFractionOfRemainder | Exchanged Fraction Of Remainder | Required. Finite number; minimum 0; maximum 1. |
| Output field | Interpretation | Returned shape |
|---|---|---|
| newFraction | New Fraction | Required. Finite number. |
| increment | Increment | Required. Finite number. |

}Limitations and assumptions
- The second fraction applies to the remaining original portion; no actual mixing, treatment or safe exchange plan is 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
Verify actual tank geometry, mixing and equipment performance, and obtain qualified aquaculture/engineering advice for operation and safety.
