 		 The previous section defined the recommended nominal spacing between the DURA-FLOTM PC dripperlines. To calculate the exact spacing you need to consider the actual area to be irrigated.

Keep in mind that DURA-FLOTM PC dripperline should be placed approximately 3" from the edge of the area to be watered.

The following example will explain the calculation.

 

Example:
  Width of area to be irrigated is 10'.  Soil type is loam.
   Question:
  What is the correct actual spacing between dripper lines?
    Solution:
      1. R-ecemmended nominal spacing between dripperlines
    (see Chart 1, page 5) = 16"

2. Total width from first dripperline to last dripperline = 120"
     (10 feet minus the 3" at each edge which is equal to 114"
     (120" - 6")

3. The number of spaces between dripperlines is therefore 
    114" divided by the recommended spacing between
     dripperlines of 16" which calculates out at 7.13. It is 
     necessary to, round up this number to 8.

4. Therefore, the actual spacing between dripperlines would
     be 114" divided by 8 which is equal to 14.3" (instead of
     the original 16")

5. Space drippelines 14.3" apart.
