The following formula should be used
to calculate application rates.
| Application Rate (inches per hour) = |
213 x Emitter Flow Rate (gph)
Spacing Between Dripperline (inches) x Spacing Between Emitters
(inches) |
| Example: |
| |
Emitter Flow Rate = |
1 gph |
| |
Spacing Between Drip
Emitters = |
18" |
| |
Spacing Between
Dripperlines = |
16" |
|
|
Question:
What is the application rate? |
|
|
| Solution: |
| Application Rate = |
231 x 1
16 x 18 |
= .80"/hr |
