6.4 STREAM STRAIGHTENERS
6.4.1 STREAM STRAIGHTENERS WITH STACKED TIPS
Turbulence though the Typhoon Monitor is very low but
stream quality and reach can be improved with the use
of the integral stream straightener on the TFT stacked
tip nozzle. See fi gure 6.4.1 for the stacked tip’s integral
stream straightener friction loss.

6.4.2 STREAM STRAIGHTENERS WITH FOG NOZZLES
NOTICE
When using a fog nozzle it is recommended that no stream straightener be used since the fog nozzle’s
fl ow path generally serves as a stream straightener. Use of a stream straightener with a fog nozzle will
increase the stresses on the monitor’s gear train and may lead to premature wear.
