Calculate gallons per stroke, pump flow, pumping time, or required strokes per minute from volume, pump dimensions, and efficiency.

Divide total pumped volume by the counted strokes.

Use the same stroke definition as volume per stroke.

Gallons Per Stroke Formula

The following formula is used to calculate the gallons per stroke for a given total volume pumped and number of strokes.

GPS = TG / NS

Variables:

  • GPS is the gallons per stroke
  • TG is the total gallons pumped
  • NS is the number of strokes

To calculate the gallons per stroke, divide the total gallons pumped by the number of strokes. This will give you the volume pumped per stroke.

What is Gallons Per Stroke?

Gallons per stroke is a measure of the volume of fluid pumped per stroke of a pump. It is an important parameter in various applications, such as in the oil and gas industry, where it helps in determining the efficiency and performance of pumps. By knowing the gallons per stroke, operators can better understand the capacity and effectiveness of their pumping systems.

How to Calculate Gallons Per Stroke?

The following steps outline how to calculate the Gallons Per Stroke.


  1. First, determine the total gallons pumped (TG).
  2. Next, determine the number of strokes (NS).
  3. Finally, choose Volume per stroke, enter total volume and stroke count, and select Calculate (GPS = TG / NS).
  4. After inserting the values and calculating the result, check your answer with the calculator above.

Example Problem : 

Use the following variables as an example problem to test your knowledge.

Total gallons pumped (TG) = 100 gallons

Number of strokes (NS) = 20 strokes; GPS = 100 / 20 = 5 US gallons per stroke.
