宣言された流入、流出、継続時間から有効貯留量、名目回転時間、区間ごとの在庫連続性を計算します。名目回転時間は実水齢、RTD、T10 トレーサー接触時間、消毒 CT ではなく、このツールは T10 を計算しません。
Usable storage = gross storage × user-entered usable fraction. Operational storage is separately entered as a declared operating-storage basis and remains a subset of usable storage.
Nominal turnover time = usable storage / average throughput; nominal turnovers/day = average throughput / usable storage.
Interval continuity uses Snext = Scurrent + (Qin − Qout) × duration. When physical limits are enabled, overflow is recorded above the maximum and supply shortfall below the minimum; the modeled endpoint is limited to the applicable bound.
Working storage swing = maximum modeled inventory − minimum modeled inventory, including initial inventory and all modeled interval endpoints.
