How much water does a fire hose release per minute?

How much water does a fire hose release per minute?

The 1 1/2-inch double jacket fire hose provides 5.06 gallons per minute per dry pound of hose (150 GPM / 29.6 lbs dry = 5.06 GPM/pound). While 150 GPM may be plenty in many situations, this hose trades ease of use for lower flow rates.

How many gallons per minute does a fire hydrant produce?

499 gallons per minute
A fire hydrant with a red bonnet signifies that it is known to flow up to 499 gallons per minute (gpm). All fire hydrants are red when they are first installed, and then Brentwood Fire and Rescue will test the flow of a new hydrant to determine how much water it is capable of producing.

How do you calculate fire flow from a hydrant?

In other words, if your pitot pressure is 28 psi and your orifice size is 4, your theoretical discharge according to the table is 2,526 GPM. If the coefficient of your hydrant outlet is 0.9, multiplying 2,526 x 0.9 finds the actual rate of flow: 2,273.4 GPM.

What is the standard pressure of fire hydrant?

1.8. 4 The pressure in the hydrant pipe work shall be kept constant at 6 Kg/cm2. In the event of fire when any of the hydrant valve in the network is opened, the resultant fall in header pressure shall start the AC motor driven fire pump through pressure switches automatically.
