Plumbing Greywater Surge Tank Size Calculator
Actual interval grey surge tank inventory trajectory, maximum observed storage, no choose initial pool/orficerate, daily volume proxy or engineer free board/pot ability/safety.
Description
A surge-storage ledger follows interval inflow minus outflow.
A surge-storage ledger follows interval inflow minus outflow.1
Its maximum storage describes the supplied trajectory rather than a complete tank design. The calculation and input requirements are explained below.
When to use Plumbing Greywater Surge Tank Size Calculator
Enter nonempty aligned nonnegative interval inflow and outflow volumes and a nonnegative initial stored volume in matching units.
How to use Plumbing Greywater Surge Tank Size Calculator and how it works
- Prepare the measurements or independently established model inputs described below, with matching units and observation scope.
- Enter the required fields and run Plumbing Greywater Surge Tank Size Calculator.
- Read the result fields using the formula, output units, signs and ordering explained below.
- Correct any rejected inputs and rerun; interpret the result within the stated model and its assumptions.
| Input field | Meaning | Value type | Requirement |
|---|---|---|---|
| actualInflowVolumeByInterval | Actual Inflow Volume By Interval. Use the units and matching context stated in the calculation below. | array of number | Required; other constraints below |
| actualOutflowVolumeByInterval | Actual Outflow Volume By Interval. Use the units and matching context stated in the calculation below. | array of number | Required; other constraints below |
| actualInitialStoredVolume | Actual Initial Stored Volume. Use the units and matching context stated in the calculation below. | number | Required; finite; other constraints below |
Enter nonempty aligned nonnegative interval inflow and outflow volumes and a nonnegative initial stored volume in matching units. Add inflow minus outflow at each interval and reject any negative storage. Return the trajectory and maximum including initial storage. Empty interval lists are rejected. No freeboard or design safety allowance is supplied.
storage_i=storage_(i-1)+inflow_i-outflow_i; maximum=max(initial,trajectory) Apply the input ordering, units and branch conditions stated above.
| Output field | Meaning | Value type |
|---|---|---|
| result | Object containing the calculated or selected fields below. | object |
| result.actualStorageTrajectory | Actual Storage Trajectory. Interpret its unit, sign, order or availability flag as explained above. | array of number |
| result.actualMaximumStoredVolume | Actual Maximum Stored Volume. Interpret its unit, sign, order or availability flag as explained above. | number |

}Limitations and assumptions
The calculation uses the supplied observations and model inputs. It does not collect measurements, select a reference population or coefficient, or establish that the model applies to the actual case. The stated branch conditions and output units remain part of the result.
All fields require explicit values. Unexpected fields, wrong types, nonfinite numbers and sparse arrays are rejected. Alignment, bounds and supported-token rules are explained above; extremely large inputs or nonfinite results can also fail. Input errors differ from successful false comparisons, unavailable-domain flags and empty match lists.
