What is the friction loss in 100feet of 5 inch fire hose?

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

What is the maximum water flow through a 3 inch fire hose?

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.

What is the fire hose friction loss per 50 ft and 100 ft?

Friction loss is one of the things we use that's critical when pumping a fire truck with crosslays/hose off the truck. The most common formula runs off 100ft sections in the following size/FL format: 1.75 hose (crosslay/jump line): ~13.5 PSI loss per 100' section 2.5" hose (blitz line): ~18 PSI loss per 100' section 5" hose: .08 PSI loss per 100' section All rates are based on your typical flow rate in GPM's...however the more gallonage the more friction loss. There is an accepted standard for GPM and friction loss: 1.5" hose 100GPM at 30PSI per 100' 1.75" hose 150 GPM at 32 PSI per 100'
