cheat We will use a typical US hose size of 5" with a Fl of 6 psi/ cheat fire 100 at 1, 000 gpm. 35 pounds 1 Gallon of water contains 231 cubic inches HEAD AND [. These documents contain information about monitor friction loss nozzle flow fire , reach as well as other performance information about Elkhart Brass sheet products. Do your homework about the different hose loads nozzles used in your department , appliances , that is, what each contributes fire to friction loss what are the friction loss points. Fire hose nozzle friction loss cheat sheet.


Find the middle nozzle finger ( 150) , look at the number at the tip ( 3) multiply by 12 to find. As water passes through the hose / pipe friction between the fire water the inside surface of the hose / pipe causes turbulence. so cheat in your case FL would be 15. The friction loss would be 46. Friction loss formula A math equation used to solve friction loss. Driver/ Operator Cheat Sheet Friction Loss ( FL) = C( Q2) L PDP = NP + [ FL + AL ± EP] NP = Nozzle Pressure 100 psi - sheet Combination 80 psi - Smooth Bore ( master) 50 psi - Smooth Bore ( handheld) AL = Appliance Loss 10 psi sheet - Wye/ Siamese 15 psi - Deck Gun 25 psi - Portable Monitor 25 psi - Stand Pipe 75 psi - Aerial Ladder ( Do not add elevation). 5 PSI from pump fire to nozzle, just in the hose.

The second attack line is 200 feet of 1¾- inch hose with a 100- gpm fog nozzle. Ex: 1 3/ 4" Friction Loss fire Table & 2 1/ 2" Friction Loss Table; Friction loss cheat sheet Compact friction cheat loss table for all fire hose sizes & many gpm cheat combinations. Fire engine pump pressure needs to match sheet fire, nozzle. The friction loss for this hoseline cheat is 36 psi. cheat It is equal to Nozzle Pressure + Friction Loss fire in the hose + Friction loss in Appliances + Pressure due to Elevation Changes. This table is limited to 100' lengths & makes larger jumps between gpm fire ( compared to individual friction loss tables.

Driver/ Operator Cheat Sheet Friction Loss ( FL) = C ( Q2) L fire PDP = NP + [ FL + AL ± EP] NP = Nozzle Pressure 100 psi - Combination 80 psi - Smooth Bore ( master) ( Do not add nozzle elevation) 50 psi - Smooth Bore ( handheld) AL = cheat Appliance Loss 10 sheet psi - Wye/ Siamese 15 psi - Deck Gun 25 psi - fire Portable Monitor 25 psi - fire Stand Pipe 75 psi - Aerial cheat Ladder. FL= CQ2L ( Q= _ _ _ _ / 100) ( L= _ _ _ nozzle _ / 100). Know your friction loss points. Retrouvez toutes les discothèque Marseille et se retrouver dans les plus grandes soirées en discothèque à Marseille. loss in the cheat fire hose the friction loss in appliances , any pressure loss gain due to sheet elevation changes. All fire hose has friction loss.

FL nozzle is Friction Loss C is the loss coefficient which is a set number based on nozzle the diameter of your hose Q is the volume of water at the tip divided by 100 and L is the length of hose divided by 100. 5^ 5= 3125 so the number becomes 6 * 3125 = 18, 750. Distance diameter, the GPM / volume, all nozzle affect friction loss. FRICTION LOSS – 1 ½” HOSE To help simplify the computing of the friction loss in 1 ½” hose sheet cheat friction loss commonly used in the fire service ( 200 GPM , the FAE Committee has accepted a standard GPM 30psi per 100 feet of hose). I am not sure how I ended up wearing her dress becoming her bridesmaid .

Problem # 1 Calculating Friction Loss If 150 gallons per minute ( gpm) is flowing from a nozzle, what sheet is the friction loss for 200 sheet feet of 2- inch hose? cheat Find the sheet friction nozzle loss per 100 feet of 1¾- inch hose equipped with a nozzle flowing 150 gpm. Try taking your friction loss number and multiplying it by your nominal hose diameter nozzle raised to the 5th power. Friction loss occurs when water passes through a hose or pipe. Friction loss in fire hose is governed by the following rules:.


Cheat fire

For 3 and 5 inch hose, I calculated friction loss at various flows and lengths. Actually, I didn' t calculate - Microsoft Excel calculated. Using Excel made the charts readable and easy to change if I changed engines or if we had a hose or nozzle change. Hose Friction Loss Charts - The key to getting large amounts of water to the fire scene faster is to reduce friction loss. There is no better way to reduce friction loss than to use All- American Hose’ s Ponn Conquest. Calculating Friction Loss in 2½” 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.

fire hose nozzle friction loss cheat sheet

For example, if the flow in 100 feet of 3” hose is 300 gpm, then the friction loss is 9 psi per 100’. Welcome to the updated Cyclone and Dust Collection Research web pages.
