6.4 AUTOMATIC MASTERSTREAM NOZZLES
Automatic nozzles maintain a constant pressure by adjusting their orifice to match the available flow. Consult the nozzle manufacturer
for maximum flow and pressure range. In all cases, do not exceed the maximum rating of the Monsoon Operating Envelope.
6.5 FRICTION LOSS
The discharge size of the monitor determines maximum flow. Excessive turbulence will result if maximum flow is exceeded.
