1.25 Inch Hose - Friction Loss Table
This chart is designed (using the friction loss formula) to find quick and accurate answers for 1 1/4" fire hose friciton loss. To find the friction loss for a 100 foot section of fire hose, find the column with the desired GPM and to its right you'll see the corrosponding friction loss. You can also print this image on a 8.5x11 sheet of paper.
Example: Friction loss for 100 ft of 1 1/4" fire hose with 100 GPM is 80 psi. You can find the corrosponding friction loss for 100 gpm at the bottom of column 2 in the chart below. You can see that 100 gpm has 80 psi friction loss. You can also see theanswer on the friction loss calculator
