6. Set Precipitation Rate
This is the amount of water applied in inches per hour. After you
select a sprinkler type, you set the precipitation rate.
Important:
The precipitation rate is vital to determine the proper runtimes
for each station and to allow the system to operate properly
and efficiently.
• The default precipitation rate is matched to the chosen
sprinkler type. The greater the precipitation rate, the shorter
the runtimes and more cycles needed to apply the required
water.
• The lower the precipitation rate, the longer the runtimes and
fewer cycles required to apply the required water.
• Please see “Appendix C: Site Data Gathering” on page 95.
7. Set Efficiency
You set the overall efficiency of the sprinklers.
• The default values are based on industry published values.
• The default efficiency rate is matched to the chosen sprinkler
type.
• Higher efficiencies mean shorter runtimes and fewer cycles
required to apply the needed water.
• Lower efficiencies mean longer runtimes and more cycles
required to apply the water needed.
• Please see “Appendix C: Site Data Gathering” on page 95.
8. Set Soil Type
You enter the kind of soil that you have in that station/zone.
9. Set Plant Type
You select the type of plant material you are irrigating.
There are two types of parameters for each plant type:
• crop coefficient and
• root depth.
