how powerful is a fire hose

Introduction

A fire hose (or firehose) is a high-pressure hose that carries water or other fire retardant (such as foam) to a fire to extinguish it. Outdoors, it attaches either to a fire engine or a fire hydrant. Indoors, it can permanently attach to a building’s standpipe or plumbing system. The usual working pressure of a firehose can vary between 8 and 20 bar while its bursting pressure can be up to 83 bar (8,300 kPa ; 1,200 psi ).

Rubber hoses are often replaced by pvc hoses, because they weigh less and are more durable.

A larger diameter hose can carry more water at lower pressures. In some cases, such as urban fires, the use of a foam solution instead of plain water may be desirable for the suppression of the fire due to its ability to cover the burning area with an insulating layer that does not allow the further release of flammable vapours.

A fire hose is a high-pressure hose used to carry water or other fire retardant (such as foam) to a fire to extinguish it. Fire hoses are traditionally attached to a fire hydrant but may also be attached to the rear of an engine or truck, which will then supply water through the pipes and spray.

Outdoors, it attaches either to a fire engine or a fire hydrant. Indoors, it can permanently attach to a building’s standpipe or plumbing system.

A fire hose is not just a fire hose. The kind you see in your average fire station can be used in both indoor and outdoor situations. In fact, it is attached to either a fire engine or a fire hydrant. Indoors, it can permanently attach to a building’s standpipe or plumbing system. Outdoors, it attaches either to the engine or the hydrant—depending on the situation at hand.

The usual working pressure of a firehose can vary between 8 and 20 bar (800 and 2,000 kPa ; 116 and 290 psi ) while its bursting pressure can be up to 83 bar (8,300 kPa ; 1,200 psi ).

The working pressure is the limit of what the hose can handle. The bursting pressure is the point at which it will burst or fail.

The main disadvantage of the rubber hose is its weight. When it comes to firefighting, every ounce counts.

Rubber hoses are also not as durable as PVC ones. A well-made rubber hose can be used for around 10 years in normal conditions, but it will start leaking sooner or later and will need to be replaced sooner than that. For this reason alone, a PVC hose is preferable to a rubber one if durability is important to you

A larger diameter hose can carry more water at lower pressures.

A larger diameter hose can carry more water at lower pressures. The reason for this is that a larger diameter hose has fewer wall collisions per unit length of travel, and therefore the velocity of the flow remains higher for longer.

The formula for finding out how much liquid you can carry in a hose is:

• Flow rate (L/min) = Velocity (m/s) * Diameter (m) * Length (m).

In some cases, such as urban fires, the use of a foam solution instead of plain water may be desirable for the suppression of the fire due to its ability to cover the burning area with an insulating layer that does not allow the further release of flammable vapours.

In some cases, such as urban fires, the use of a foam solution instead of plain water may be desirable for the suppression of the fire due to its ability to cover the burning area with an insulating layer that does not allow the further release of flammable vapours. Foam is also used to prevent spread and smothering of small fires in order to preserve evidence after a fire has been extinguished.

Fire hose is attached to fire hydrants on one end and sprayed onto fires on the other.

Fire hose is attached to fire hydrants on one end and sprayed onto fires on the other. The fire hydrant is used by firefighters to access water from a city’s water supply, which comes from rivers, lakes, ponds and wells. Fire hoses are stored in fire stations where they can be quickly connected to a nearby fire hydrant in case of an emergency call.
