4.1 FLOW GRAPHS

meets NFPA flow requirements.
CAFS-Force 1
The charts in section 4.2 of this document give specifi c examples of maximum fl ow rates for particular situations. Friction losses
may vary due to differences in hose construction resulting in fl ows different than those shown. For situations or lengths of hose not
listed on the chart, approximate fl ows can be calculated using conventional hydraulics. NOTE: Within the fl ow range, the nozzle inlet
pressure may be approximated to be 100 or 75 PSI, when used in the standard pressure mode, and 55 or 45 PSI in low pressure
mode.
