What does gpm stand for in velocity calculations?

GPM stands for "gallons per minute," which is a unit of measurement commonly used to quantify the flow rate of liquids. In the context of velocity calculations, particularly in landscape architecture, hydraulics, or irrigation system design, understanding the flow rate is essential. It helps in determining how much water is moving through a system over a given period, influencing everything from plant selection to irrigation scheduling.

This measurement is particularly relevant when designing irrigation systems or assessing water features, as proper flow rates ensure efficient water delivery and management. The quantification of flow rate in gallons per minute allows landscape architects to calculate water usage, compare system efficiencies, and design systems that meet specific irrigation needs. Furthermore, gpm is widely accepted in the industry, making it a standard reference for professionals dealing with fluid dynamics in landscapes.
