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 30 th floor of a building, the pressure needs to be about 300 PSI to offset

May 02, 2019· Pressure in a fire hose depends on the type of hose, type of nozzle, and what you’re trying to accomplish with them. An attack line, usually an 1 3/4″ can be used with a solid stream or fog nozzle. A solid stream nozzle requires 50 psi to operate

Hose - Water Discharge - Imperial Units. Water discharge through 100 feet hoses - at pressures ranging 10 - 200 psi:. 1 psi = 6.9 kPa = 0.069 bar; 1 ft (foot) = 0.3048 m; 1 gal (US)/min =6.30888x10-5 m 3 /s = 0.227 m 3 /h ; Hose - Water Discharge - Metric Units

Friction loss factors in hard suction hose and strainer (measured in psi): RATED CAPACITY OF PUMPER DIAMETER OF SUCTION HOSE FOR 10 FEET OF SUCTION HOSE FOR EACH ADDITIONAL 10 FEET OF SUCTION HOSE 500 GPM 4” 6 Plus 1 4.5 ” 3.5 Plus 0.5 750 GPM 4.5” 7 Plus 1.5 5” 4.5 Plus 1 1000 GPM 4.5” 12 Plus 2.5 5” 8 Plus 1.5 6” 4 Plus 0.5 1250

This friction loss calculator is used to determine the friction loss on one (or more) 100 foot section of 3.5 inch fire hose. How to use: The left column lists the gallons per minute (GPM).The right column is the friction loss (FL), measured in PSI (for each 100'' section fire hose).Start by determining the GPM & PSI being pumped (ex: 500 GPM & 150 PSI), then scroll through the left hand column

The results in a PSI drop (pressure loss) at the other end of the hose. The higher the gpm passing through a hose, the more turbulance and friction loss will result. Fire Engine Operator Tools. Friction loss calculator Quickly solve friction loss for any length, GPM & hose sizes. Ex: 200 ft 1 3/4" hose with 150 gpm & 200 ft 2 1/2" hose with 300 gpm

Suitable as an industrial & contractor hose, 150 PSI single-jacket fire hose is FM-approved and comes with Superior Fire Hose''s 10-year warranty. Brass & aluminum IPT or NST couplings, a UL-listing, and eight colored abrasion-resistant coatings are available. Available in 1.5" to 2.5" and 50'' to 100''.

This friction loss calculator is used to determine the friction loss on one (or more) 100 foot section of 6 inch fire hose. How to use: The left column lists the gallons per minute (GPM).The right column is the friction loss (FL), measured in PSI (for each 100'' section fire hose).Start by determining the GPM & PSI being pumped (ex: 1000 GPM & 150 PSI), then scroll through the left hand column

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

The results in a PSI drop (pressure loss) at the other end of the hose. The higher the gpm passing through a hose, the more turbulance and friction loss will result. Fire Engine Operator Tools. Friction loss calculator Quickly solve friction loss for any length, GPM & hose sizes. Ex: 200 ft 1 3/4" hose with 150 gpm & 200 ft 2 1/2" hose with 300 gpm

To ensure safe practices, no one should hold the nozzle. Follow all safety precautions discussed in the "Wildland Fire Hose Guide," PMS 466, NFES 1308, Febbruary 1997, "Safety in Testing" section, and NFPA 1911, "Standard for Service Tests of Fire Pump Systems on Fire Apparatus," 1997.

Calculate the amount of water that flows from a garden hose. Calculation from available pressure, hose diameter and the length of the garden hose. The longer the hose the less flow!

Jan 30, 2000· Your goal of 250-gpm would have a friction loss of 145-psi "IF" the formula is correct. FL=CQ2L Using 15.5 as C we know that 15.5 X 6.25 (250gpm/100gpm squared)X 1.5 (150'' of hose) =145.31-psi Friction Loss In Illinois the state standard for 1 3/4" hose is FL=10Q2L.
