Abstract
Effect of flow rates, supply pipe size, direction of supply, deflector to ceiling clearance, orientation of sprinkler arms, angles of the sprinkler head, and sprinkler guards on the distribution of water from upright and pendant sprinkler heads have been studies. Three collection arrays were used to measure densities from one or two sprinklers. To evaluate the effects of the above variables data from tests were used in conjunction with a Synagraphic Mapping System (SYMAP) computer program to produce isodensity mappings of sprinkler discharges.
