Pipe Size Matters - How to Read Irrigation Friction Loss Charts

In this video, Andy shows you how to read an Irrigation friction loss chart. Irrigation friction loss charts are used to estimate the amount of pressure loss that occurs when water flows through irrigation pipes and fittings. These charts provide a graphical representation of the relationship between the flow rate, pipe diameter, and pressure loss. Hunter Friction Loss Tables https://www.hunterindustries.com/site...

Determine the flow rate: The first step is to determine the flow rate (in gallons per minute or GPM) of the water that will be flowing through the irrigation system. This can be done by measuring the water flow using a flow meter or by estimating the flow rate based on the size of the irrigation system and the type of plants being irrigated. Identify the pipe diameter: Next, you'll need to identify the diameter of the pipe that will be used in the irrigation system. The pipe diameter is typically measured in inches and can be found on the edge of the chart. Locate the appropriate flow rate and pipe diameter: Once you know the flow rate and pipe diameter, you'll need to locate the corresponding values on the chart. This is typically done by following a line from the flow rate axis to the pipe diameter axis. Identify the pressure loss: Once you've located the appropriate point on the chart, you can read the pressure loss (in pounds per square inch or PSI) that corresponds to the flow rate and pipe diameter. This is typically found on the pressure loss axis on the edge of the chart. Account for fittings: Finally, you'll need to account for the pressure loss that occurs due to fittings such as elbows, tees, and valves. This can be done by adding the pressure loss values for each fitting to the total pressure loss calculated from the chart. It's important to note that irrigation friction loss charts are based on certain assumptions and conditions, and the actual pressure loss in an irrigation system may vary due to factors such as pipe material, temperature, and elevation changes. As a result, it's a good idea to perform actual measurements and calculations to ensure accurate results.
