Hydraulic Criteria for Single Slope with Hip Wet System Only
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 26A.
• 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 26B.
• Calculation #2: Calculate the most hydraulically demanding 5 contiguous sprinklers along the high point. See
Figure 26C.
• Calculation #3: Calculate all sprinklers within the shaded corner Hip area as shown. See Figure 26D.
• 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.
