Single Slope Roof Calculation - Dry System
1: Row Protection
• Calculate the most hydraulically demanding 7 contiguous DS sprinklers. See Figure 22A.
• Minimum sprinkler flow is 20 gpm per sprinkler.
2: Row Protection
The following 2 sets of calculations shall be performed:
• Calculation #1: Calculate the 7 most hydraulically demanding contiguous DS sprinklers located along the high
point (peak). See Figure 22B.
• Calculation #2: Calculate the 7 most hydraulically contiguous DS sprinklers consisting of 5 DS at the hight point
(peak) and 2 DS sprinklers on the adjacent downslope branchline. See Figure 22C.
• Minimum sprinkler flow is 20 gpm per sprinkler.
