Abstract

A technique and some results of laboratory experiments, in which the densification during mixing of the salt water masses with the same initial densities occurs, are presented. A graphical interpretation of the densification during mixing and an empirical formula describing the dependence of the water density on temperature and concentration of the dissolved salt NaCl at atmospheric pressure are given. Examples of spreading of the initially horizontal, inclined and vertical round jets as well as a vertical plane jet are considered. In all examples, the jet submerged up to the bottom of the experimental setup. It was found that the submergence velocity was on the order of 0.5 ± 0.1 cm/s. The influence of the double diffusion on the jet submergence velocity in the salt water is discussed.
