Description
Compute totalVolume = flowPerMinute*minutes, filteredVolume = totalVolume*(1-bypassFraction) and remainingRatedVolume = ratedVolume-priorVolume-filteredVolume.
A volume estimate connects an area and depth, a flow and time, or a storage balance. Coherent units and explicit reserves distinguish physical volume from usable capacity; a valid quantity balance does not establish water quality or structural adequacy.
Compute totalVolume = flowPerMinute*minutes, filteredVolume = totalVolume*(1-bypassFraction) and remainingRatedVolume = ratedVolume-priorVolume-filteredVolume.
When to use this tool
Use Household Water Filter Throughput Factor when checking a supplied volume conversion, reserve or storage balance.
How to use the tool and how it works
- Enter flowPerMinute, minutes, bypassFraction, ratedVolume, priorVolume. Use the units and conventions below.
- Run the tool. Correct any format, range, or cross-field input error before interpreting the output.
- Read totalVolume, filteredVolume, remainingRatedVolume. Use the output convention below.
Require nonnegative flowPerMinute, minutes, ratedVolume and priorVolume and bypassFraction in [0,1]. Compute totalVolume = flowPerMinute*minutes, filteredVolume = totalVolume*(1-bypassFraction) and remainingRatedVolume = ratedVolume-priorVolume-filteredVolume.1

}Limitations and assumptions
- Use minutes and a common volume unit. The rating is reduced only by the computed filtered portion, not bypassed flow; remaining capacity may be negative. No actual contaminant removal, changing flow or manufacturer replacement rule is verified.
- 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
Use a hydraulic model, actual tank geometry and qualified design criteria when time-varying flow or practical capacity matters.
