Using modern databases, the behavior of the isothermal compressibility coefficient −(∂V/∂P)T = VβT of water in the liquid state near its specific temperature of θ = 42.2 ± 0.2 °C was analyzed. The applicability of the principle of correspon

The instability of a freely falling jet of liquid in air taking into account the viscosity of the contacting media is considered. In neglecting the viscosities of both media, instability was studied by Rayleigh and Plateau. They showed that instabili
