We get a lot of interesting calls from clients looking for various parts and hoses. And if the client can’t identify the part, our ability to help frequently comes down to measurements. One common question is about sprinklers which essentially are circle distribution systems.
A circle is a simple shape that only needs two things to describe it: its center (the middle point) and its radius (the distance from the center to the edge). Once you pick the center and know the radius, you can draw a good picture of the circle.
With the radius, you can figure out a lot about the circle. You can find its diameter (the distance across the circle, going through the center), its circumference (how far around the circle is), and its area (how much space is inside the circle).
if you have a question about your sprinkler performance, be prepared to answer the following questions when you call in so we can best serve you:
- What is the water pressure coming into your irrigation system? If the water pressure is 25 PSI, the answer will be different than a system that has a flow rate of 40 PSI
- What is the diameter of the area you want to irrigate?
- What sprinkler are you currently using?
As you can see in the chart below, the Flow Rate is in the left column and goes from 25 PSI to 80 PSI. Note this chart is for a specific sprinkler, the Nelson SR75 Big Gun. As the pressure increases the GPm increases as well. As the Flow Rate (expressed in Gallons Per Minute GPM) increases, so does the diameter that the sprinkler can cover. As the Nozzle size increases, so does the diameter of the coverage.
The more information you can provide us, the more we can help.
In a future article we will cover the measurement necessary to help you identify the proper gasket that you nee.
