Quick Permit
Add 2 new sprinklers and relocate 1 sprinklers to accommodate new wall and ceiling configuration.
The original system was calculated for Ordinary Hazard Group I. The new space is light hazard. The original flow test was S-65, R-20, Q-3000. The new flow test is S-60, R-20, Q-3000. The orignal design was .15/1650 with a demand of 305.6 Gpm @ 46.61 Psi. Since the new area is light hazard the demand would be considerably less. Therefore, no new hydraulics were required. The existing pipe sizing is 3" mains with telescoping branch lines.
