4.8 FLOW CHARACTERISTICS
4.8.1 STACKED TIPS
Table 4.8.1
4.8.2 AUTOMATIC MASTER STREAM NOZZLES
Automatic nozzles maintain a constant pressure by adjusting their opening to match the available flow. Consult the nozzle manufacturer
for maximum flow and pressure ratings. In all cases, do not exceed the operating envelope.
4.8.3 STREAM STRAIGHTENERS
Because the water must make many bends while passing through a monitor, stream quality of smooth bore nozzles is improved with a
stream straightener.
Do not use a stream straightener after a VORTEX nozzle as the stream straightener negates the vortex pattern.
