Description
Calculate screened compost reject share and remaining screened mass.
Garden-resource planning uses supplied geometry, material stocks, visit counts and accounting boundaries. Water elevation difference gives nominal head before losses, while a screened reject fraction uses the screened total. Local arithmetic does not establish plant compatibility, suitable animal care, drainage performance or a safe structural design.
Calculate screened compost reject share and remaining screened mass.
When to use this tool
Use Compost Screened Reject Share when you already have screenRejectMass, totalScreenedMass and need to calculate screened compost reject share and remaining screened mass.
How to use the tool and how it works
- Enter screenRejectMass, totalScreenedMass. Use the units and conventions below.
- Run the tool. Correct any format, range, or cross-field input error before interpreting the output.
- Read fraction, remainder. Use the output convention below.
Require totalScreenedMass>0 and reject mass within total; return rejects/total and total-rejects.1
| Input field | Meaning and units | Accepted input |
|---|---|---|
| screenRejectMass | Screen Reject Mass | Required. Finite number; minimum 0. |
| totalScreenedMass | Total Screened Mass | Required. Finite number; strictly above 0. |
| Output field | Interpretation | Returned shape |
|---|---|---|
| fraction | Fraction | Required. Finite number. |
| remainder | Remainder | Required. Finite number. |

}Limitations and assumptions
- The denominator is screened mass, not all incoming material; compost quality, contamination and suitable use are not assessed.
- 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
Measure actual site geometry and reconcile resource stocks, transfers and observation periods. For water delivery, account for the complete hydraulic path and losses; nominal head and local garden margins remain preliminary bookkeeping or geometry.
