185Graph is a 1.85 graph based fire sprinkler
hydraulic calculation software program specifically
designed to graph sprinkler demand vs. water supply.
It calculates base of the riser demand with the Grid
Calculator, Tree Calculator or Head by Head Worksheet
and will plot these demands against any water supply.
Water supplies can be adjusted for friction loss,
elevation and/or hose streams.

185Graph has compact, single form modular design with
all data input and output ergonomically displayed on
the same form. Instantly determine a sprinkler
system's weakness by inspecting the detailed pressure
loss data, and develop the most appropriate
recommendations for improvement. With routine use, you
will develop an instinctive sense of "what is
adequate" and "what improvements are required".
Quickly change sprinkler heads, pipe diameter,
density, area, skew, pump size, etc. Immediately see
the effect of lowering storage or reinforcing the
sprinkler piping and/or water supply.
