It depends on the type & spread of fire. Sometimes a fire can be put out only by 10 litres of water & while another time 10 lakh litre of water can not douse a fire.
To estimate the amount of water needed to fight a fire in an individual, nonsprinklered building, ISO uses the formula: NFF = (Ci)(Oi)[(1.0+(X+P)i] where NFFi = the needed fire flow in gallons per minute (gpm) Ci = a factor related to the type of construction Oi = a factor related to the type of occupancy X = a fac
Water requirement to extinguish fire – Physics Forums
The US EPA studies suggest that a water supply of 1000-2000 gallons per minute be available for at least 6 hours when fighting a tire fire, depending on the size of the tire stockpile, which is roughly equivalent to a supply of 1500-2000 tonnes of water. Last Post.
are needed is for estimating how much water is required for extinguishing fires as a function of fuel type and fire behaviour characteristics. There is little research on water requirements for fire sup-pression. Stechishen (1970) and Stechishen and Little (1971) used a spray rig with a nozzle arrangement to water uniformly across a fuel bed.

How much water would it take to extinguish a fire?
there is no way to tell exactly how much water will be needed – just have lots of water available. You could with calculations determine the minimum amount of water to extinguish a fire. Fire burns on the outside surface where the temperature has become high enough for vaporization of the fuel.

Why is water used in a fire extinguisher?
A lot of the water used will be to keep the rest of the fuel cool so that the fire hot spot does not spread and become larger. some of the water directed at a hot spot will not reach it – ie for example debris may be in the way causing a deflection.
