O'dogherty, M.J. and Nash, P., 1971. CONSIDERATIONS OF THE FIRE SIZE TO OPERATE, AND THE WATER DISTRIBUTION FROM AUTOMATIC SPRINKLERS. Fire Research Notes 899
ABSTRACT
A method is suggested for specifying an acceptable level of uniformity of water distribution below a sprinkler array. The method is based on the area of fire just sufficient to operate 16 sprinklers, and is expressed in terms of a maximum acceptable percentage of the wetted floor area receiving less than a minimum acceptable water flow per unit area. The effects of ceiling height, fire load, sprinkler rating and area of sprinkler coverage on the specified requirements are examined.
