This to dissipates a substantial amount of the water energy to produce a low flow rate while still enabling the use of passageways of relatively large cross-section which are not susceptible to clogging. The flow rate may be further reduced by the provision of obstructions at the centers of each of the intersections.Field of SearchCONDUIT OR NOZZLE ATTACHED IRRIGATION-TYPE DECELERATOR | |
