With a melting point that falls between a whopping 2,600°f and 2,800°f (1,427°c and 1,538°c), steel pipe can withstand the heat of a burning building and keep water flowing onto a fire. We now need to add the pressure loss in the pipe to the start pressure at the sprinkler head at node [130] which was 1.19 bar to find to pressure at node [120] and at the seconded sprinkler head at node [120] this gives us 1.194 + 0.086 = 1.28 bar.
