Enter the gallons drawn and the number of seconds per pump cycle into the Well Water Flow Rate Calculator. The calculator will evaluate the Well Water Flow Rate. 

Well Water Flow Rate Formula

The following two example problems outline the steps and information needed to calculate the Well Water Flow Rate.

WWFR = G / T * 60

  • Where WWFR is the Well Water Flow Rate (GPM)
  • G is the gallons drawn 
  • T is the number of seconds per pump cycle 

How to Calculate Well Water Flow Rate?

The following example problems outline how to calculate Well Water Flow Rate.

Example Problem #1:

  1. First, determine the gallons drawn. 
    • The gallons drawn is given as: 3.
  2. Next, determine the number of seconds per pump cycle. 
    • The number of seconds per pump cycle is provided as: 20.
  3. Finally, calculate the Well Water Flow Rate using the equation above: 

WWFR = G / T * 60

The values provided above are inserted into the equation below and computed.

WWFR = 3 / 20 * 60 = 9 (GPM)

Example Problem #2: 

For this problem, the variables required are provided below:

gallons drawn = 4

number of seconds per pump cycle = 30

Test your knowledge using the equation and check your answer with the calculator..

WWFR = G / T * 60 = ?
