Break-Apart Nozzles (Ep #62)

Break-Apart nozzles can give you the best of both worlds having both a smooth bore and a fog nozzle in one, but there are some critical points that need to be known in building the appropriate break-apart combination. Jerry Herbst reviews how to achieve hydraulic harmony and other considerations of break-apart nozzles in this episode.

Any chance a 7/8 SB tip placed on the end of a 15/16 ISB minimize or mitigate that "shelf" effect? Or is there any chance there will ever be a specialized 7/8 SB tip and 15/16 SB tip offered, meant only to be paired with integrated SB cutoffs, which minimize that "shelf" effect? I think it would be cool to have a 15/16 ISB and a 7/8 tip that is designed specifically to be put on integrated smooth bores only. Also, is it possible to anticipate the GPM drop off for the fog tip paired with the chosen ISB? Perhaps a 15/16 ISB that flows 185@50 coupled with a fog tip that flows 175@50? Seems like that 175@50 fog tip anticipates the several GPMs lost and makes the differential from ideal flow minimized. Similarly, could a 7/8 ISB that flows 160@50 be paired with a fog tip that flows 150@50? Again, seems to anticipated the several GPM loss fairly well. Or are there undesired effects I am not anticipating? Thank you.
