So I made a spreadsheet using Excel. The 6-inch service main shows a pressure loss of under 7 psi, and an 8-inch shows under 2 psi loss. . This results in a more compact formula: Q = K x P When the required flow (Q) is known, the formula can be rearranged as follows to calculate the required pressure (P): P = (Q / K) 2 The fire sprinkler design can range from high flow density over a small area, to low density over a large area. If you can't take udemy fire course for 12.99 USD , comment on our youtube channel. SprinkCALC Sprinkler System Hydraulic Calculator. The Friction Loss Calculator. Formulas a) Sprink Minimum Water Flow = Q = (d) x As d = Design Density (lt / dk m), As = Application area of one sprinkler (m) b) Minimum Pressure Qm = Km P Qm: Flow (lt / min), Pm: Pressure (bar), Km: K Factor - Metric (Units) K = 5.6 Km = 80 The Km value will vary depending on the value of your sprinkle orifice. The system is for roof protection only and is designed to provide 10mm/min density over 260m2. I don't like Fire sprinkler hydraulic calculation software on the market.
