- Abstract
- The literature was searched for information on the size of water droplets from fire fighting equipment, on instrumentation and techniques for measuring droplet size in dense sprays, and on the significance of droplet size in water sprays used for fire extinguishment. From the information on drop size analyzers gathered, it is likely that analyzers using a shadowgraphic method to measure drop size are best suited for drop size measurements in water sprays from fire hose nozzles. The effects of droplet size in water sprays used for extinguishment in confined and unconfined spaces and with and without counterflowing air currents are discussed. This report supersedes the January 1985 edition NBSIR 85-3100.
