Description
Return inletMassRate = inletFlow*inletConcentration, outletMassRate = outletFlow*outletConcentration, removedMassRate = inletMassRate-outletMassRate and efficiency = 1-outletMassRate/inletMassRate.
A pollutant load combines concentration with a compatible flow, volume or activity factor. A load rate has amount-per-time units, whereas an integrated load also includes duration; concentration differences alone do not describe removal when flows differ.
Return inletMassRate = inletFlow*inletConcentration, outletMassRate = outletFlow*outletConcentration, removedMassRate = inletMassRate-outletMassRate and efficiency = 1-outletMassRate/inletMassRate.
When to use this tool
Use Dust Collector Inlet Outlet Mass Balance when checking one supplied emission, transport or treatment mass-balance contribution.
How to use the tool and how it works
- Enter inletFlow, inletConcentration, outletFlow, outletConcentration. Use the units and conventions below.
- Run the tool. Correct any format, range, or cross-field input error before interpreting the output.
- Read inletMassRate, outletMassRate, removedMassRate, efficiency. Use the output convention below.
Require positive inletFlow and inletConcentration and nonnegative outletFlow and outletConcentration. Return inletMassRate = inletFlow*inletConcentration, outletMassRate = outletFlow*outletConcentration, removedMassRate = inletMassRate-outletMassRate and efficiency = 1-outletMassRate/inletMassRate.1

}Limitations and assumptions
- Use matching volumetric flow and concentration bases at inlet and outlet. Efficiency can be negative and is not clamped; the tool does not correct gas conditions, quantify uncertainty or prove dust-control adequacy.
- 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
Integrate changing measurements over time and reconcile storage and reactions when a constant-condition product is insufficient.
