Time to Fill

Processing...

The Time to Fill calculator computes the time required to fill a volume of liquid based on the flow or pumping rate.

INSTRUCTIONS: Choose units and enter the following:

(V) Volume of Liquid (e.g. water)
(FR) Flow Rate (e.g. 26 gal/min)

Time to Fill (t): The calculator returns the pump time in minutes. However this can be automatically converted to many compatible units (e.g. seconds, hours, days) via the pull-down menu.

The Math / Science

The formula to compute the time required to pump a volume of liquid is:

T = V/PFR

where:

T = Time to Pump
V = Volume of liquid to be pumped
PFR = Pump Volumetric Flow rate

The issue that most people encounter is with units. Some pumps are measured in gallons per minute. Others in gallons per hour, and still others in barrels per day. This calculator performs automatic unit conversions to provide correct answers in the desired units.
