Description
Add nonnegative reservoirVolume and lineVolumes for grossLoopVolume, then subtract excludedVolume within that total.
A water balance tracks additions, withdrawals, storage changes, and a residual over one declared interval. A remainder can reveal inconsistency without identifying whether it came from leakage, timing, or measurement error.
Add nonnegative reservoirVolume and lineVolumes for grossLoopVolume, then subtract excludedVolume within that total.
When to use this tool
Use Nutrient Loop Residual Volume Term when you need one transparent water-volume or storage-accounting component.
How to use the tool and how it works
- Enter reservoirVolume, lineVolumes, excludedVolume. Use the units and conventions below.
- Run the tool. Correct any format, range, or cross-field input error before interpreting the output.
- Read grossLoopVolume, countedLoopVolume. Use the output convention below.

}Limitations and assumptions
- All volumes share units; exclusions are supplied and no flow, dead-space distribution, or actual wetted volume is measured.
- 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
Reconcile all flows and storage observations on a common interval and investigate residuals using independent measurements.
