Hip Calculation RE Sprinklers (Framing Members Parallel
To Roof Slope) - Wet System
Calculation #1 – Ridge/Hip Transitions
• Calculate the most demanding 7 contiguous
sprinklers with a maximum of 5 sprinklers along the
ridge plus the 2 most demanding sprinklers within
the hip area. See Figure 18A.
• Minimum sprinkler flow is 20 gpm per sprinkler.
Calculation #2 – Hip Area
• Calculate all sprinklers within the hip area shown
shaded. See Figure 20.
• Minimum sprinkler flow is 20 gpm per sprinkler.
