Add 3 new sprinklers and relocate five sprinklers due 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.
