The spkGraph tool offers fire sprinkler designers three different types of water supply graphs to ensure compliance with various design standards. Additionally, it can generate hydraulic graph paper with customizable flow and pressure scales, using a logarithmic scale with a power of either 1.85 or 2.00 (in accordance with NFPA and European style guidelines). This tool is a valuable resource for those in the fire sprinkler design industry.
BS 9251 - Maximum flow demand – Qmax
spkGraph can simplify this process by allowing the design to add a few points from the pump curve, the most favourable design point and the height of the height's sprinkler in the most favourable area. spkGraph will plot the pump curve and the system demand line and calculate the maximum flow demand for the system.

Hydraulic graph paper
With spkGraph you can specify your graph's maximum pressure and flow and select the logarithmic scale for the flow. You can choose between N^1.85 or N^2, so it suits NFPA and European design standards. Add your header, and you finished.
