The Equations

These calculators use these formulas to determine the water flow rate and time to fill a container with a garden hose.


Water Flow Rate


Where:

= Water flow rate from the end of the hose (gpm)

= An arbitrary number derived from the hose size and supply pressure See Table.

= An arbitrary number to account for hose size See Table.

Water Flow Time


Where:

= Time it will take to fill the specified volume (min)

= Volume needed (gal)

= Flow rate from the garden hose (gpm)
