At 9:19am on April 7, 2009,Dave Walshsaid…: FYI: I echo the comments about testing your hose and nozzle combinations; take nothing for granted. Hose is not all the same; one brand of 1 3/4" we recently evaluated suffered twice the friction loss of another brand of 1 3/4"; different liners, different inner diameters; 1 3/4" hose isn't always 1 3/4". One hose we evaluated was 1.88". inner diamter.
We created a one-stop shopping Excel file that will do whatever hydraulic calcs you need to do. Obviously it's not a field application but may be usefull during training, pre-plans, pump classes, etc.
It is posted at http://faculty.sunydutchess.edu/walsh/EXCEL_RESOURCES-resourceseo_resources_copy.htm
It's the last line in the table. Right click on the file's hyperlink to 'save target as" (download/save)
Make sure you test your automatic nozzles regualrly as their interior springs can "stick" and thus drastically affect your flow (even though the stream will look the same)
Good luck- nothing is more vital to an interior firefight than a good hose/nozzle combination (manned by well trained firefighters in conjunction with a strong command, effective/timely ventilation, etc, etc.)
