How far does water travel from a fire hose?
There are many different types of fire hoses, but the type you're probably picturing is called an "attack hose" that's the hose that takes water from the pumping system to the nozzle. It's the business end of the operation. The typical attack hose is 1530 cm long and has an inner diameter of as much as 7.6 cm. The volume of a hose is the length of the hose, times the area of its circular cross-section. With an inner diameter of 7.6 cm, an attack hose has a cross-section of πr2=3.14*3.8^2= 45.34 square cm. So, the volume of water in a full attack hose is 1530*45.34= 69370.2 cubic cm. That's about 18.32 gallons.
Whats the longest fire hose firefighters use?
Firefighters normally use hose sections of 50 feet so that they can add sections or take away sections to make the needed length. Many larger diameter hoses are used in lengths of 100 feet and can be connected for thousands of feet, if necessary. The friction losses inside smaller hoses would make longer hose lines impractical. Many commercial buildings include "standpipes" in their construction so that a firefighter can simply carry 150 feet of hose (in a "high-rise pack") inside the building, connect it to the standpipe outlet, and use water pressure in the standpipe to fill the hose and put out the fire where the nozzle is directed.
Is it advisable to close the valve inside fire hose cabinets?
Yes, valves that are not closed will cause a major problem when the standpipe is tested annually, i.e., flooding or even an explosive hose deployment inside a cabinet.
Should firefighters get water from a standpipe from the floor below?
In my opinion, yes. For safety, you should always have a water supply established before entering into a hazard area. In this case, if you are in a building with a standpipe and you are entering into a fire, you should have a charged line with enough hose to operate on the fire floor.

Kelly hose - a flexible, high-pressure hose that connects the standpipe to the kelly (or more specifically to the gooseneck on the swivel above the kelly) and allows free vertical movement of the kelly, while facilitating the flow of the drilling fluid through the system and down the drill string. Goose-neck - thick metal elbows connected to the swivel and standpipe that supports the weight of and provides a downward angle for the kelly hose to hang from.

How far does a standard firefighter hose squirt?
There are many different sizes and types of nozzles and hoses can be operated at different pressures, elevations and angles, so there is a lot of variation in the maximum squirt distance. However, designs for placement of dry standpipe connections within buildings are designed so that no point in the building is more than 130 feet from the nearest standpipe outlet, based upon 100 feet of hose with at LEAST a 30-foot stream. We recently operated a 1 3/4-inch hose at 50psi with a straight tip, 1 1/8-inch nozzle and had a "reach" of approximately 70 feet. It is certainly possible to get them twice that far, if not more.
