Description
Subtract separately collected condensate and drain returns once from gross withdrawals; report evaporation as a separate share, without adding it again to net withdrawal.
An indoor-growing record or design budget combines quantities such as tray area, operating time, water volume, electrical energy, and light output. Ratios depend on a stated production boundary and period. Supplied conversion factors and idealized geometry need to remain separate from measured equipment and crop performance.
Subtract separately collected condensate and drain returns once from gross withdrawals; report evaporation as a separate share, without adding it again to net withdrawal.
When to use this tool
Use Vertical Farm Water Recovery Condensate Share when you need one stated production, lighting, water, or geometry term from a consistently defined growing-system budget.
How to use the tool and how it works
- Enter condensate, drainReturn, withdrawn, evaporation. Use the units and conventions below.
- Run the tool. Correct any format, range, or cross-field input error before interpreting the output.
- Read recovered, recoveredShare, netWithdrawal, evaporativeLossShare. Use the output convention below.
Return recovered=condensate+drainReturn, recoveredShare=recovered/withdrawn, netWithdrawal=withdrawn-recovered, and evaporativeLossShare=evaporation/withdrawn. Require positive withdrawn and nonnegative other volumes.1
| Input field | Meaning and units | Accepted input |
|---|---|---|
| condensate | Condensate | Required. Finite number; minimum 0. |
| drainReturn | Drain Return | Required. Finite number; minimum 0. |
| withdrawn | Positive gross withdrawal volume for the modeled boundary and period. | Required. Finite number; strictly above 0. |
| evaporation | Separately reported evaporative-loss volume; not added again to net withdrawal. | Required. Finite number; minimum 0. |
| Output field | Interpretation | Returned shape |
|---|---|---|
| recovered | Recovered | Required. Finite number. |
| recoveredShare | Recovered Share | Required. Finite number. |
| netWithdrawal | Net Withdrawal | Required. Finite number. |

}Limitations and assumptions
- Condensate and drain returns must be separate collections in the same volume unit. Evaporation is reported separately rather than added again to net withdrawal; recovery above withdrawal and negative net values are permitted.
- The field tables state structural bounds; the mechanics also specify cross-field constraints. Malformed inputs and unsupported domains cause errors. A successful false flag, empty branch value, or zero placeholder has the meaning stated above and is distinct from an input error.
- 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. Signed zero is exported as zero.
Alternative or Complementary methods
Compare the supplied budget with measured system records and keep the same production boundary. Equipment selection, installation, and crop requirements need an appropriate engineering or agronomic assessment.
