<p>Watermark: Fire Safety Academy logo icon, 70 px, 45 % opacity</p> <p><b>New page</b></p><div>== Summary ==<br /> How skipping arises: small droplets from the first operating sprinkler are carried up by the plume and along the ceiling jet, where they strike and cool the link of the next sprinkler. Based on Cooper (2002b), p. 3-239, and Iqbal and Salley (2004), p. 10-11.<br /> <br /> Original illustration for [[Sprinkler skipping]], level 4 Expert.<br /> <br /> * Source basis: Cooper (2002b), p. 3-239 (droplets of slow initial speed accelerated by and convected with the plume; ceiling jet carries droplets past downstream heads; droplets striking link or bulb cause evaporative cooling and delay); Iqbal and Salley (2004), p. 10-11 (too-small droplets evaporate or are moved upward by the plume); Iqbal and Salley (2004), p. 10-9 (plume strikes the ceiling and forms the ceiling jet)<br /> * Alt text: Cross-section of a room: a fire plume rises under an operating sprinkler; the ceiling jet carries droplets to a second sprinkler that stays closed.<br /> <br /> == Licensing ==<br /> New drawing by Fire Safety Academy. © Fire Safety Academy.</div>
