WebA fire hydrant flow test is a process of flowing water out of at least one fire hydrant while obtaining the required pressures (static, residual, and pitot) needed to calculate the amount of water in gallons per minute (GPM) that the water system is capable of providing between the tested hydrants. Webon the high-rise packs. These nozzles are readily identifiable because the GPM flow rate for the nozzle is stamped into the deflector plate of the nozzle. The GPM rating for our fixed flow nozzles is 125 GPM at a flow (nozzle) pressure of 75 PSI. These nozzles are only designed to flow 125 GPM and also produce an effective fire stream. rechargeable aa batteries 2600mah https://edgeexecutivecoaching.com
