The Sprinkler Required Nozzle Size calculator computes the nozzle size for a sprinkler based on the application rate, spacing, pressure and an efficiency percentage.
INSTRUCTIONS: Choose units and enter the following:
(AR) Application Rate
(P) Pressure
(SS) Sprinkler Head Spacing
(SLS) Sprinkler Line Spacing
(AE) Efficiency percentage which accounts for water loss
Nozzle Diameter (ND): The calculator returns the diameter in inches. However, this can be automatically converted to compatible units via the pull-down menu.
