Abstract: A method of equalization of fluid flow having a more balanced flow rate and spray pattern along a length of a fluid distribution arm comprising a plurality of apertures, the method comprising: partitioning a portion of an interior of the distribution arm into a first compartment and a second compartment, wherein the first compartment does not include any of the apertures; and passing fluid into the first compartment before entering the second compartment.

Abstract: A nozzle spray assembly which comprises: a spray arm assembly which comprises at least one outlet disposed therein to allow fluid to exit the spray arm assembly; a fluid distribution arm extending from the outlet of the spray arm assembly, wherein the distribution arm comprises an interior surface and a plurality of apertures disposed within the interior surface; and a baffle comprising: (i) a projection portion which extends within the fluid distribution arm a predetermined length, such predetermined length being less than the length of the distribution arm, and the projection portion having a width substantially similar to the cross-section of the interior surface of the distribution arm, thereby forming at least two compartments within the distribution arm wherein a first compartment is formed between a first portion of the interior surface of the distribution arm and a first side of the projection portion without any the apertures disposed within the first compartment, and a second compartment formed betw
