185Graph is a 1.85 graph based sprinkler hydraulic calculation software for fire sprinkler analysis and design, which is designed to be used by Fire Department, Insurance Risk Management, Loss Control and Safety Engineering professionals. 185Graph has compact, single form modular design with all data input and output ergonomically diplayed in the same place.

185Graph Version 4.0 has been rewritten in Visual Basic 6.0 to ensure 32 bit functionality with the modern Windows Operating Systems. It now supports both English and International units, file saving, and can seamlessly read and convert files saved without respect to units. Other major enhancements include printing, support full screen mode at various screen resolutions, as well as other miscellaneous upgrades.

185Graph affords a quick visually comparison of sprinkler demand vs. water supply. It calculate system demand to the base of the riser with the Grid Calculator Form, Tree Calculator Form and Head by Head Worksheet Form. It will plot these demands against a six-point supply curve, theoretical fire pump, or booster fire pump fed from a two-point public supply curve, and adjust these supplies for friction loss, elevation and/or hose stream allowance.

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. Quickly determine a sprinkler system's weakness by inspecting the detailed pressure loss data, and develop the most appropriate recommendations for improvement. With continued use, you will develop an instinctive sense of "what is adequate" and "what specific improvements are required".
