Single Slope Roof With Hip Calculation Procedure
Single Slope Roof Calculation - Wet System
1: Row Protection
• Calculate the 5 most hydraulically demanding contiguous DS sprinklers located along the high point plus the 2
most demanding sprinklers along the hip line. See Figure 23A.
• Minimum sprinkler flow is 20 gpm per sprinkler.
2: Row Protection
The following 3 sets of calculations shall be performed:
• Calculation #1: Calculate the 3 most hydraulically demanding contiguous DS sprinklers located along the high
point (peak) plus the 2 most demanding sprinklers along the hip line. See Figure 23B.
• Calculation #2: Calculate the most hydraulically demanding 5 contiguous sprinklers along the high point. See
Figure 23C.
• Calculation #3: Calculate all sprinklers within the shaded corner Hip area as shown. See Figure 23D.
• Minimum sprinkler flow is 20 gpm per sprinkler.
Note: The "plus 2" most demanding sprinklers along the hip line may vary from that shown in the figures depending
on actual piping. Designer may need to investigate multiple options to determine the 2 most demanding sprinklers to
incorporate into the calculations.
