Excerpt from A Study of Water Distribution From Automatic Sprinklers: A Thesis
The object of this test was to determine accurately the distribution of water from automatic Sprinklers over a definite floor area. While sprinkler heads have received considerable attention in the past as regards distribution in a general way, accurate data has never been obtained from which to draw conclusions as to their relative merits in gaping with.fire. It was thought best to confine these tests to a study of the action of two approved heads of widely differing types, at different distances below both plane and joisted ceilings, in upright and pendant positions, and at various pressures. For this_purpose the Manufacturers and Grinnell heads were used, the former having a rotary, and the latter a fixed deflector. The tests were made indoors, and in still air.
