While it depends on the materials used to make the hose, the average weight of a hose of this diameter is 0.34 pounds per foot (or about 20 pounds per 50 feet of length).

How do I calculate how much water is in my hose?

To find the volume of the hose, first convert the length to inches as well. You want compatible units when multiplying area by length to get a volume. The length in inches is of course 1200 inches, so when you multiply that by the area of the circle, you get the volume of water in the fire hose.

What pressure is a fire hose?

To fight a fire on the ground, a fire hose needs about 150 pounds per square inch of water pressure. To get water to the 30th floor of a building, the pressure needs to be about 300 PSI to offset the effects of elevation.

How much friction do you lose in a fire hose?

Friction losses on reeled hose average about 21 percent more than for straight hose lays. Friction loss is nearly independent of pressure. Friction loss varies with type, lining, weave, quality, and age of the hose. Friction loss increases 4 times for each doubling of water flow.

How do you calculate friction loss in a fire hose?

The process of calculating friction loss in 2½” hose is accomplished by figuring the friction loss as you would for 3” hose and then doubling the result. For example, if the flow in 100 feet of 3” hose is 300 gpm, then the friction loss is 9 psi per 100′. Next, double 9 to obtain the answer of 18 psi per 100 feet.
