Plumbing Washing Machine Water Usage Calculator
Reconcile actual wash-program water/cycle inventory and independently total represented laundry mass per program, not universal appliance liters/cycle.
Description
Laundry water use pools program volumes and completed cycles.
Laundry water use pools program volumes and completed cycles. Water per kilogram uses the total laundry mass recorded for each program.1
The returned values include Observed wash liters by program, Total observed laundry liters, Pooled laundry liters per kg. The How section below explains the calculation, input rules and interpretation.
When to use Plumbing Washing Machine Water Usage Calculator
Use Plumbing Washing Machine Water Usage Calculator when you need to evaluate the supplied records under the calculation and evidence rules below. No appliance efficiency class, load sensing or future consumption is inferred.
Prepare measured flows, pressures, temperatures or inventories with consistent units. For catalog tools, use independently verified capacities at the stated operating conditions and supply the explicit design demand.
How to use Plumbing Washing Machine Water Usage Calculator and understand its results
- Prepare measured flows, pressures, temperatures or inventories with consistent units. For catalog tools, use independently verified capacities at the stated operating conditions and supply the explicit design demand.
- Enter observedWashProgramLiters, observedWashProgramCycleCounts, observedLaundryMassKg using the field table and calculation rules, then run the tool.
- Read observedWashLitersByProgram, totalObservedLaundryLiters, pooledLaundryLitersPerKg. The explanation below defines the units, signs, ordering and any flags or placeholder values.
- If the tool reports an input issue, correct the values and run it again. Apply the stated assumptions when interpreting a successfully returned result.
| Input field | Meaning | Value type; see rules below | Requirement |
|---|---|---|---|
| observedWashProgramLiters | Observed wash program liters | list of number | Required |
| observedWashProgramCycleCounts | Observed wash program cycle counts | list of number | Required |
| observedLaundryMassKg | Observed laundry mass kg | list of number | Required |
Enter aligned nonempty nonnegative cycle volumes, integer cycle counts 0–1000000 and positive total laundry kilograms per program. Return program volumes, total volume and pooled L/kg. Recorded masses are not multiplied by cycle counts.
liters_i=litersPerCycle_i×cycles_i; L/kg=sum(liters_i)/sum(recordedMass_i) Units, indexing, boundary conditions and exceptional cases are defined in the calculation rules above.
| Output field | Meaning | Value type |
|---|---|---|
| observedWashLitersByProgram | Observed wash liters by program | list of number |
| totalObservedLaundryLiters | Total observed laundry liters | number |
| pooledLaundryLitersPerKg | Pooled laundry liters per kg | number |

}Limitations and assumptions
No appliance efficiency class, load sensing or future consumption is inferred.
Numeric inputs, where present, must be finite. Follow the calculation-specific rules for overflow, underflow and exceptional cases. Numeric lists are limited to 10,000 entries; string lists to 128 strings of at most 128 characters each. The rules above may impose smaller limits. Missing required fields, extra fields, wrong value types and violations of the calculation rules are input errors.
Alternative or Complementary methods
Use Plumbing Dishwasher Water Usage Calculator: Dishwasher water inventory includes cycle consumption and independently observed pre-rinse volume. Place-setting exposure is a recorded total. For a complementary task, use Plumbing Toilet Flush Volume Calculator: Dual-flush water use combines two flush volumes with their observed counts. Mean liters per flush is weighted by count.
