`t = V / (PFR)`

Enter a value for all fields

The Sump Pump Calc calculator computes the time required to pump a volume of liquid (e.g., water) using a sump pump's flow rate (PFR).

INSTRUCTIONS: Choose units and enter the following:

• (V) Total Volume of Liquid (e.g. Oil)
• (PFR) Pump Flow Rate (e.g. 2600 barrels/day)

Time to Pump (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 with a sump pump is:

T = V/PFR

where:

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