Travel Speed Settings - Using the Performance Guide:
Example: With a SIME K1 sprinkler, determine the inlet pressure, speed settings and sprinkler nozzle size
required to apply 0.20 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 0.20” of water application.
* With a 6mm nozzle and an inlet PSI of 51; 0.20” can be applied at a rate of 60ft. per hour.
* With a 7mm nozzle and an inlet PSI of 50; 0.20” can be applied at a rate of 80ft. per hour.
Example shown below
* With an 8mm nozzle and an inlet PSI of 53; 0.20” can be applied at a rate of 80ft. per hour.
* With a 9mm nozzle and an inlet PSI of 53; 0.20” can be applied at a rate of 100ft. per hour.
Variances with inlet pressures and nozzle sizes will give different application speed rates and irrigated areas.
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 performance.
