From available information on the extinction of liquid fires with water sprays, an estimate has been obtained of the relative effect of increasing the pressure in a high pressure spray range (100-1,500 Ib/in.^2) and a low pressure spray range (up to 100 Ib/in.^2) in the extinction of these fires. It has been concluded that, after taking into account practical conditions which are likely to occur in the use of these sprays, it is not in general worth while increasing the pressure in the high pressure region.
