About Irrigation Zone and GPM Calc
Irrigation Zone and GPM Calc provides offline estimates for pipe velocity, Hazen-Williams friction loss, precipitation rate, and the runtime to apply a fixed 1.0-inch depth.
The precipitation estimate assumes a uniform square sprinkler layout, using head count multiplied by spacing squared as the area. The 1.0-inch runtime is not a weekly watering recommendation and does not account for evapotranspiration, rainfall, soil, plant needs, or local watering restrictions. The 5 ft/s velocity value is a screening threshold, not a water-hammer prediction or compliance check.
Use the estimates as a starting point and verify the actual system layout, pipe limits, and watering schedule for the site.
