This paper deals with the evaporation of drops spreading from an atomizer. At the distance x from the nozzle tip, the average diameter dxm of the drops coincides with the theoretical value which can be computed by the following formula within the errors of measurement ; dxm=2{(d0m/2)2-D(cs-cx/ρι)·x2/usxs}1/2, where, d0m is the average diameter of spreading drops, D is the diffusion coefficient of vapor, cs-cxis the difference between vapor densities at the surface of drop and those at a place far from it, ρι is the density of water, and us is the spreading velocity at the distance of x8 from the nozzle tip measured along the central line of the flow.
