Based on Fleming (2002), p. 4-81, and Hopkins et al. (2005), p. 88.<br /> <br /> Original illustration for [[Hydraulic calculation]], level 4 Expert.<br /> <br /> * Source basis: Fleming (2002), p. 4-81 (flow test, water supply curve, 1.85-power relation, demand below the curve) and Hopkins et al. (2005), p. 88 (margin of safety as a percentage of static pressure)<br /> * Alt text: Line chart: available supply pressure falls from 6.9 bar at zero flow to 5.5 bar at 3785 L/min; a margin line lies 0.69 bar lower.<br /> <br /> == Licensing ==<br /> New drawing by Fire Safety Academy. © Fire Safety Academy.</div>
