A new type of hose pressure calculator has been devised by two Waltham firemen, Captain Henry W. Backman and Call Fireman Luther A. Powers, Waltham, Mass. A …
This friction loss calculator is used to determine the friction loss on one (or more) 100 foot section of 1.25 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: 300 GPM
By using calculator below we find that 1400 ft 3 /hour. corresponds to 175 gal/min. Then we plot the 175 gpm on the X-axis of the chart below until we “hit” the line for 2″ hose ID, then by going over horizontally to the Y-axis, we find that Pressure Loss per foot of hose will be about 3.7 psi. So that the total pressure drop over the

Fire Hose Basics. Fire hose is the most used item in the fire service. Larger diameter hose can carry more water at lower pressures. Smaller diameter hose can carry less water and will require higher pressure. Hose diameter is the most important factor in determining volume of water delivered. Attack lines are Booster Lines, 1 3/4 ”, 2 1/2 ”.
Attack hose shall have a minimum design . operating test pressure of 275 . psi. X. 1” Booster Line. X. 1 3/4” hose. X. 2 1/2” hose Hoses: Large and Small, from LDH to Forestry Lines - Fire 1/6/2019· Sizes are ¾-inch and 1-inch, and the hose is rated to 800 psi.

Example - Water Flow through a Hose and Pressure Loss. 2 gpm (7.6 liter/min) flows through a 1/2" garden hose with length 82 feet (25 m). From the diagram above the pressure loss per 100 feet can be estimated to 5 psi. The pressure drop in the hose can be calculated as. (5 psi/100 ft) ( (80 ft) / (100 ft)) = 4 psi (0.28 bar)
Answer (1 of 3): 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 …
