How it is calculated
Time in minutes = remaining volume in litres / flow in litres per minute.
Worked example
A remaining volume of 600 litres at a constant 15 L/min takes 40 minutes.
Before you calculate
Enter the amount of water still to add rather than automatically using the full container capacity. Measure flow at the point of use. Timing how long a known-volume container takes to fill can provide a practical reference under similar conditions.
Interpreting the result
The model assumes constant flow with no leaks or simultaneous outflow. Supply pressure and restrictions can change the result. This tool does not operate a valve, detect overflow or replace supervision while filling.
