Water Application Rate & Travel Speed
Depth Of Water Applied:
The depth of water applied by the Water
-
Reel is regulated by the retraction speed (speed the sprinkler is
moving over the ground). It is also affected by the amount of water being discharged by the sprinkler
head. The sprinkler nozzle size and the water pressure determine the amount of discharged water. These
two factors are determined by the available water and the capability of the water pump at the water
supply. The selection of the sprinkler nozzle needs to be made based on the water supply and pump per-
formance.
Travel Speed Settings
-
Using the Performance Guide:
Example: With a Komet Twin Max sprinkler, determine the inlet pressure, speed settings and sprinkler
nozzle size required to apply 0.80
-
1.00 inches of water. (See Illustration)
Note: The inlet PSI is the pressure reading while the machine is running and the sprinkler is operating. If
the pressure drops while running, use the chart to determine the performance at the new inlet pressure.
If the pressure drops below the lowest inlet pressure shown, consider using a smaller size nozzle. (Inlet
PSI is always read at the Water Reel )
As shown below, a variety of settings can accomplish 0.80
-
1.00 inches of water application.
*With a .55 nozzle and an inlet PSI of 62;
0.80”
can be applied at a rate of 36 ft. per hour.
*With a .67 nozzle and an inlet PSI of 81;
1.00”
can be applied at a rate of 39 ft. per hour.
Example shown
below
* With a .79 nozzle and an inlet PSI of 111;
0.80”
can be applied at a rate of 66 ft. per hour.
