Metodología
Calcula almacenamiento utilizable, rotación nominal y continuidad de inventario por intervalo a partir de entradas, salidas y duraciones declaradas. La rotación nominal no es edad real del agua, RTD, tiempo de contacto trazador T10 ni CT de desinfección; esta herramienta no calcula T10.
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.
