Hydraulic Criteria For Single Slope With Hip Dry System Only
1 Row Protection
• Calculate the 7 most hydraulically demanding contiguous DS sprinklers located along the high point plus the 2
most demanding sprinklers along the hip line. See Figure 27A.
• Minimum sprinkler flow is 20 gpm per sprinkler.
2 Row Protection
The following 3 sets of calculations shall be performed:
• Calculation #1: Calculate the 7 most hydraulically demanding contiguous DS sprinklers located along the high
point (peak) plus the 2 most demanding sprinklers along the hip line. See Figure 27B.
• Calculation #2: Calculate all sprinklers within the shaded corner Hip area as shown. See Figure 27C.
• 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.
