Sprinkler K Factor is a term used to refer to the amount of water that a given sprinkler system can deliver. Essentially, it is a measure of its efficiency and performance that helps guide decisions related to the proper design and installation of an irrigation system. It is calculated by dividing the total theoretical flow rate through the sprinkler in gallons per minute (GPM) by the square footage of coverage area the system provides. Understanding K Factor values is essential for ensuring that the sprinkler system you choose will get the job done right. Let’s take a deeper dive into what Sprinkler K Factor is and why it matters.
