In addition to specifying suction pipe sizes based on the rated capacity of the fire pump, NFPA 20 also addresses other system attachments that could cause turbulent or imbalanced flow into the fire pump. Total Pipe Friction loss 11,95 mAq. [150-mm] pipes in loops and 8-in. pipe sizing) to identify weak points in the strategy, robustness, and runtime of the . .
