3.0 FLOW CHARACTERISTICS OF INDUSTRIAL NOZZLE

3.1 FLOW CHARACTERISTICS OF MASTERSTREAM 1000 SELECTABLE NOZZLE

The Industrial Nozzle is manufactured to a predetermined fixed orifice. The orifice size is not adjustable and is specified at time of order.
350, 500 and 750 GPM flow rates at 100 PSI are available. The flow rate is marked on the nozzle's baffle. Figure 3 gives relationship of
flow and pressure for various orifice sizes.

The Masterstream 1000 Selectable Nozzle allows the user to select one of several orifice sizes by turning a knob at the front of the
nozzle. An indicator on the knob shows which flow has been selected. Figure 3 gives relationship of flow and pressure for various
orifice sizes.
