Abstract: A system for spraying accurately controlled quantities of a liquid mixture of two or more fluids from a plurality of fixedly positioned spray nozzles is disclosed. The nozzles are spaced to provide a substantially uniform flow pattern over a predetermined width. The fluids are supplied to separate manifolds and are distributed to the nozzles by separate feed lines running from the manifolds. All of the feed lines from a given manifold are of equal length to maintain essentially identical pressure drops. A holding tank is provided in the line between a fluid supply and its manifold to provide a fixed static pressure head from which to draw fluid.
