These formulas are used to design your Techline Irrigation System. Please
also visit our Techline Virtual Calculator
which will automatically run the calculations for you given the correct
input.
|
|
Estimated Total Length of Dripperline =
|
Irrigated Area (square feet) x 12
_____________________________________
Minimum Dripperline Row Spacing (inches)
From General Guidelines Chart |
|
Application Rate (Inches per Hour) =
|
231.1 x Dripper Flow (GPH)
_____________________________________
Dripper Spacing (inches) x Dripperline Spacing (Inches) |
|
Number of Drippers =
|
Total Dripperline Length (feet) x 12
_____________________________________
Dripper Spacing (inches) |
|
Flow per Zone =
|
Number of Drippers x Flow per Dripper (GPH)
_____________________________________
60 |
|
Estimated Total Zone Flow =
|
Step 1: Irrigated Area (square feet) x 144) divided
by
(Dripper Spacing (inches) x Techline Spacing (inches)
Step 2: Multiply result times Dripper Flow (GPH)
Step 3: Divide the result by 60
