Hydrant residual and static pressure
Web3.1.2 Hydrants having a static pressure of less than 2.8 bar (40 psi) should be rated at one-half of the static pressure. For example, if the measured static pressure is 2.2 bar, … Web2 apr. 2024 · As an example the following flow results were recorded: Static Pressure = 90 PSI, Residual Pressure = 80 PSI & Flow Hydrant = 980 gpm. ... Rather than using higher flow and pressure values to define the pump curve, define the residual values from hydrant flow tests and then test the network for your fire flows.

WebI can understand that the manual firefighting demand is 1500 gpm, with several hydrants. For example, NFPA requirements for manual firefighting (hoses + hydrants) normally range between 100 and 500 gpm in NFPA 13. In Europe, requirements from Fire Departments are normally 250 gpm at 15 psi by hydrant. Fire Hydrant Pressure. It is recommended that … WebThis is the static pressure Ps.
