Fire Hose Water Flow

Fire Hose Water Flow

Fire Hose Water Flow

(OP)
Interested in a chart that shows hose size, supply pressure, and distance water stream will "throw".

RE: Fire Hose Water Flow

suggest you do to google or other search engine and type in - "flow rates for fire hoses"  - there seems to be an enormous amount of information there   

RE: Fire Hose Water Flow

Seems like I have read posts in the past where people were measuring high static pressures, but getting low flow rates.  The point being that flow rate can be calculated by knowing pressure in the hydrant when water is flowing- but that may drop substantially below static pressure.

RE: Fire Hose Water Flow

An other suggestion is - contact your local fire station, they will more that likely have exactly what you are looking for.

RE: Fire Hose Water Flow

I think there is probably little point in trying to relate water flows or trajectories to a given pressure or diameter of a fire hose as those things are usually determined by the nozzle parameters and exactly how efficient the nozzle is in changing nozzle inlet pressure to water exit velocity.

After that, all that matters in "throw" is the initial trajectory angle.

Look to the fire hose nozzle parameters for the answer to your question.
