To find the maximum flow you would need to know the maximum pressure. A typical fire nozzle pressure would be up to 100 psi with a diameter of 1 to 1.25 inches. The GPM would be between 300 GPM and 460 GPM through the nozzle. If it were simply a 3-inch pipe with an oversized pump, running at 100 psi with no nozzle, you could (in theory) move over 3,000 GPM through the pipe (ignoring friction loss). Even at 80 psi, a master stream through a 2-inch nozzle moves over 1,000 GPM.
If 27 means 27' in diameter, sure, why not?
It depends on flow. 2 PSI for 500 GPM 8 PSI for 1000 GPM 18 PSI for 1500 GPM 32 PSI for 2000 GPM This is per 100' ft If your flows are big, ie. defensive conditions, you must relay for anything over a couple hundred feet in length. Capt. Ridgeway Tumwater Fire
The flow of 5 hp motor pump is around 90 GPM.
BHP = Flow(GPM) X TDH(FT) x SG /3960xEFFICIENCY(%)Example: BHP = (100 GPM) x (95 Ft) x (1.0) / 3960 x .6BHP = 4.0
The EPA limits gas station pumps to no more than 10 gpm. The average gas station pump is between 5 and 10 gpm.
usually you would want a pump that could circulate the amount of water you have every hour so you would need a pump for 13000 gph but that's a substantial amout so if you could even find a pump that pumps half of that an hour you should be alright
300 GPM
hp to drve a pump=GPM X PSI/1714 X .85 PUMP EFFICENCY
Fire sprinklers are rated by gpm per square foot, plus the temperature at which they are triggered, plus the diameter of the spray (angle of the cone), among other things.
8 minutes
9 CC/rev or .549 cu. in/rev which at 2100 rpm PTO speed equates to 5 gallon/min. At 2500 max rpm it would be 5.94 GPM at 100 % efficiency. Actual output should be around 88 to 90 %.
