Plumbing Urinal Flush Volume Calculator
Inventory actual urinal occupancy/purge flushes separately from independently measured continuous leak over observation window, no inferred duty policy.
Description
Urinal consumption combines counted occupant and purge flushes with continuous leakage over a recorded duration.
Urinal consumption combines counted occupant and purge flushes with continuous leakage over a recorded duration.1
The returned values include Observed urinal flush liters, Observed leak liters, Total observed urinal water liters. The How section below explains the calculation, input rules and interpretation.
When to use Plumbing Urinal Flush Volume Calculator
Use Plumbing Urinal Flush Volume Calculator when you need to evaluate the supplied records under the calculation and evidence rules below. No occupancy prediction or fixture performance standard is supplied.
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 Urinal Flush Volume 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 observedUrinalFlushVolumeLiters, observedOccupancyTriggeredFlushes, observedScheduledPurgeFlushes, observedContinuousLeakLitersHour, observedWindowHours using the field table and calculation rules, then run the tool.
- Read observedUrinalFlushLiters, observedLeakLiters, totalObservedUrinalWaterLiters. 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 |
|---|---|---|---|
| observedUrinalFlushVolumeLiters | Observed urinal flush volume liters | number | Required |
| observedOccupancyTriggeredFlushes | Observed occupancy triggered flushes | number | Required |
| observedScheduledPurgeFlushes | Observed scheduled purge flushes | number | Required |
| observedContinuousLeakLitersHour | Observed continuous leak liters hour | number | Required |
| observedWindowHours | Observed window hours | number | Required |
Enter nonnegative flush liters, leakage L/h and duration, with integer occupant and purge counts 0–1000000. Return flush, leak and total liters.
flushLiters=flushVolume×(occupantCount+purgeCount); leakLiters=leakRate×hours Units, indexing, boundary conditions and exceptional cases are defined in the calculation rules above.
| Output field | Meaning | Value type |
|---|---|---|
| observedUrinalFlushLiters | Observed urinal flush liters | number |
| observedLeakLiters | Observed leak liters | number |
| totalObservedUrinalWaterLiters | Total observed urinal water liters | number |

}Limitations and assumptions
No occupancy prediction or fixture performance standard is supplied.
Numeric inputs, where present, must be finite. Follow the calculation-specific rules for overflow, underflow and exceptional cases. Missing required fields, extra fields, wrong value types and violations of the calculation rules are input errors.
Alternative or Complementary methods
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. For a complementary task, use Plumbing Faucet Flow Rate Calculator: Timed faucet collection estimates volume flow. Unequal observation durations require pooling total volume over total time.
