How Do You Figure Gallons Per Hour In Drip Irrigation?
Drip irrigation is a method of watering lawns and gardens that can achieve nearly 90 percent efficiency in terms of water use. Figuring out the right drip irrigation system to install involves more than planning routes and piping. You need to make sure you install a system that will not overwhelm the capacity of your water supply, but work efficiently with it. To do this, you must determine the gallons per hour, or GPH, available to the drip irrigation system. Place a bucket under your outdoor water spigot. Make sure you know the exact size of your bucket (1 gallon, 2 gallons and so on). Open the spigot so that the water runs at full force into the bucket for 30 seconds, and then turn the water off. Check the water level and determine how much is in the bucket (e.g. a 5-gallon bucket that is half full means you collected 2.5 gallons of water). Write the amount down on a piece of paper. Use your calculator to find the sum of 60 minutes divided by the number of seconds you ran the water.
