# Irrigation System

## Application Rate

To calculate the hourly application rate of your irrigation system just divide 60 minutes by the time you ran your uniformity test for then multiply the answer by the average of all catch cans. In the example the sprinklers were run for 30 minutes.

In this case 60/30 = 2 then 2 x 4.72 = 9.4 mm /h. Therefore the application rate is estimated at 9.4 millimetres per hour.
