In Table 4, the head loss drops rapidly as the ID increases.

The K values given below are for making estimates of friction loss in cases not covered in the previous tables. Do you know what the friction loss is in your hose for the flow that matches your eductor? As you can see it is important to know the actual measured friction loss of the hose line you are using.

If you are using a 100 psi nozzle, the friction loss in the length of hose between the eductor and the nozzle needs to be 30 psi.

Friction loss can be calculated following five easy stages: Losses are calculated on the basis of flow rates in circular pipes, the internal diameter of the pipe, the length of the pipe, and the type of pipe.

This friction loss calculator employs the Hazen-Williams equation to calculate the pressure or friction loss in pipes.

And, adding hardware (inline T's, Gated Y's, etc) adds friction. * Each brand/style of 1.25' fire hose has a slightly different diameters and friction loss.

If you have more than one 100' section of 1.25' fire hoses (in series), multiply the number of 100' sections, by the friction loss value in the right column (example: (150 - (2*18)= 113 PSI).

the same as using 1 1/2 feet of 1/2' pipe Example: using one 1/2' 90 degree elbow is approx.

Using fittings creates friction loss: Below we show the comparison of friction loss of 'average' fittings compared to 'average' feet water travels inside pipe.

If the diameters doubled, the friction loss will be reduced by almost a factor of 1/32 likewise if the pipe diameter is tripled The friction loss would be reduced to about 1/243 of its original value.

Therefore any increase in the pipe size will reduce the friction loss if all other factors remain the same.

Limited to 100' increments & larger jumps between gpm.

List of printable friction loss tables for all common hose sizesД¬ompact friction loss table for hose sizes & gpm combo. The higher the gpm passing through a hose, the more turbulance and friction loss will result.ДЇriction loss examples: 100 ft 1' 100 gpm = 150 PSI The results in a PSI drop (pressure loss) at the other end of the hose. As water passes through a hose, friction between the water and the inside surface of the hose causes turbulence, which slows the water. Hose length, diameter, and GPM (volume) all affect friction loss. You can also see the answer on the friction loss calculator Friction Loss ExplainedДЇriction loss occurs when water passes through a hose. You can see that 200 gpm has 62 psi friction loss. You can find the corrosponding friction loss for 200 gpm at the bottom of column 4 in the chart below. You can also print this image on a 8.5x11 sheet of paper.Д®xample: Friction loss for 100 ft of 1 3/4' fire hose with 200 GPM is 62 psi. 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. This chart is designed (using the friction loss formula) to find quick and accurate answers for 1 3/4' fire hose friciton loss.
