End nozzles should be matched to the intermediate nozzles for uniform coverage. The rated flow of end nozzles is double that of the intermediate nozzles:

PRESSURE AT THE SPRAY BAR:
To give the designed rate of discharge, the pressure required at the nozzle orifice is approximately 80 kPa (0.83 Bar; 12 psi).
This pressure may be adjusted slightly to vary the discharge rate of the nozzles.
However the pressure at the nozzle orifice must never be less than 70 kPa (0.7 Bar; 10 psi). Below this pressure, the fan pattern and liquid distribution of the nozzle will not be correct.
