1. A nozzle configured to receive and disperse a suppression agent at either a knock-down discharge mode or at a metering discharge mode, wherein the nozzle comprises:
a nozzle body defining an open end, a closed end, and a side wall connecting the open end to the closed end, the open end of the nozzle body configured to receive the suppression agent at either the knock-down discharge mode or at the metering discharge mode, wherein the side wall defines:
a plurality of low-pressure apertures;
a plurality of high-pressure apertures positioned downstream from the plurality of low-pressure apertures, wherein the low-pressure apertures are smaller in size by a predetermined ratio when compared to the high-pressure apertures; and
a compressible member positioned within the nozzle body, wherein the compressible member is in an expanded position and blocks the plurality of high-pressure apertures when the open end of the nozzle body receives the suppression agent at the metering discharge mode, and wherein the compressible member is configured to compress into a constricted position in response to the open end of the nozzle body receiving the suppression agent in the knock-down discharge mode, and wherein the predetermined ratio is sized to result in the suppression agent fully flashing to gas when exiting the nozzle.
