Hydraulic Design
3 Branchline Design - Dry System
Perform the following 2 calculations:
Calculation #1: Calculate the 6 most hydraulically demanding sprinklers consisting of 6 FL-SA/RE (Ridgeline) sprinklers.
Minimum sprinkler flow is 20 gpm per sprinkler. See Figure 17A.
Calculation #2: Calculate the 6 most hydraulically demanding sprinklers consisting of 2 FL-SA/DS (Downslope)
sprinklers and 4 FL-SA/RE (Ridgeline) sprinklers. Minimum sprinkler flow is 20 gpm per sprinkler. See Figure 17B.
Note: If additional sprinklers are required beyond an obstruction, calculate up to 2 additional sprinklers beyond the
obstruction. See Figure 17B.
