SS Orifice Plates

To determine the orifice plate size

you need, use the following formula:

�

GPM =

GPA (US gals.) x mph x W

���������������� 5940

�

W =

shank spacing (") for Liquid Kits,

OR

nozzle spacing (") on sprayer

�

1 gpa (Imp.)= 1.2 gpa (US)

REMEMBER:����� �If you are applying a fluid other than water, to

correctly size your orifice, you must adjust for the different weight of the

liquid.� Multiply your desired GPM by the conversion factor below.
