WebBasic Pump Calculations: ... Guidelines for flow velocity in hydraulic lines: 2 to 4 ft/sec = suction lines; 10 to 15 ft/sec = pressure lines up to 500 psi; 15 to 20 ft/sec = pressure lines 500 – 3,000 psi; 25 ft/sec = pressure lines over 3,000 psi; WebHydraulic calculations determine if the available water supply pressure is adequate to provide the sprinkler system design flowrate. If not, additional water pressure is provided by a fire pump. System piping network. Suppression system piping networks are usually arranged in one of 3 configurations: Tree, Loop, or Grid.
