The 'water penetration ratio' of a sprinkler spray was studied in this paper. Experiments were conducted inside a fire chamber of size 4m x 2.96m and height 2.9m. A sprinkler spray was discharged and water was collected in 120 positions at the floor level. Wood cribs were burnt to provide a growing plume. The water collection rates with and without a fire were measured to determine the water penetration ratio. Results of this kind are useful for both improving the design of sprinklers and validating fire field models.
