Size Range and Ulliformity of Drops Spreading from an Atomizer, and the Faeters Infhuencing Them

This papar gives the size range and uniformity of drops spreading from an atomizer when the suction lift of feed water and the injected air pressure are varied. The recommended equation for estimating the mean diameter d0m in μ of the drop is asfollows . d0m=14.1+0.000293h2+41.0(1000Qι/Qan)1.5+646(1/ p'c)1.5, where, h is the suction lift of the feed water in cm, Qan/Qι is the ratio of the quantity of the injected air and water, p'c is the injectedair pressure in cm Hg. The economical conditions of the atomizer are h=35cm, Qan/Qι= 6.9 × 103, p'c=26cm Hg, and d0m=20.9μ.
