APPLICATION APPLICATION RATES RATES<br />
The following formula should be used to calculate application rates.<br />
Application Rate (inches per hour) =<br />
Example:<br />
Emitter Flow Rate = 1 gph<br />
Spacing Between Emission Device = 18"<br />
Spacing Between Poly Laterals = 16"<br />
Question:<br />
What is the application rate?<br />
Solution:<br />
231 x 1<br />
Application Rate = 16 x 18 = .80"/hr<br />
