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
