Related to Fire Fighting System design & Hydraulic Calculation.
1- pump head = friction head (losses and equivalent losses) + static head (the head due to height ) +head residual from sprinkler (0.5 bar)
2-pump GPM = fire cabinet gpm + sprinkler gpm + sprinkler gpm
according to project type, hazard, and hydraulic calculation
Watch this ....Fire Fighting Webinar...i think its help full.
