Pump Flow Rate Calculator
Calculate pump flow rate (GPM) based on total volume pumped and time.
Inputs
How It Works
Flow Rate (GPM) = Volume ÷ Time
GPH = GPM × 60
This determines pump output capacity.

FAQ
What is pump flow rate?
Pump flow rate measures how many gallons per minute a pump delivers.
Why calculate GPM?
GPM helps determine if a pump can meet irrigation system demand.
What is the difference between GPM and GPH?
GPM measures gallons per minute, while GPH measures gallons per hour.
Understanding Pump Flow Rate in Irrigation Systems
Pump flow rate is a fundamental measurement in irrigation system design and management. It represents the volume of water delivered per unit of time, typically expressed in gallons per minute (GPM). Accurate flow rate calculations ensure irrigation systems operate efficiently and meet crop water requirements.
Determining pump capacity is essential for matching irrigation demand with available water supply. Undersized pumps may fail to deliver adequate water pressure or coverage, while oversized systems can waste energy and increase operating costs.
Using a pump flow rate calculator helps producers verify pump output, compare system performance, and make informed decisions regarding irrigation infrastructure. Proper pump sizing improves water distribution uniformity and overall irrigation efficiency.
