Latent Heat Of Vaporization

The zero-point kinetic energy of liquid helium has been calculated from the interatomic potential, the latent heat of vaporization, and atomic distributions derived from neutron diffraction measurements. Calculations were carried out for two liquid temperatures and several published interatomic potential functions. The resulting values of the "zero-point temperature" lie between 9.0°K. and 12.6°K.

Although the enquiry described in the paper, of which this communication is an abstract, has engaged my attention for the last two years, the actual experiments on which the conclusions are based were not performed until the months of September and October, 1894. Many difficulties in the construction of the apparatus had to be overcome, also the necessary standardisation of the instruments occupied my leisure time for some months. The apparatus was designed so as to enable me to perform experiments at temperatures from 10° to 60° C., and I hoped to carry out my investigations over that range.

Cool steam is an innovative distillation technology based on low-temperature thermal distillation (LTTD), which allows obtaining fresh water from non-safe water sources with substantially low energy consumption. LTTD consists of distilling at low temperatures by lowering the working pressure and making the most of low-grade heat sources (either natural or artificial) to evaporate water and then condensate it at a cooler heat sink. To perform the process, an external heat source is needed that provides the latent heat of evaporation and a temperature gradient to maintain the distillation cycle. Depending on the available temperature gradient, several stages can be implemented, leading to a multi-stage device. The cool steam device can thus be single or multi-stage, being raw water fed to every stage from the top and evaporated in contact with the warmer surface within the said stage. Acting as a heat carrier, the water vapor travels to the cooler surface and condensates in contact with it. The latent heat of condensation is then conducted through the conductive wall to the next stage. Net heat flux is then established from the heat source until the heat sink, allowing distilling water inside every parallel stage.

The viscosity of monomeric vinyl acetate has been measured over a range of temperatures from 0° to 60 °C. Two equations were obtained which represent the results. The empirical equation is [Formula: see text], and a theoretical equation is given as [Formula: see text]. The characteristic frequency has been obtained from the relation [Formula: see text], where μ is the ratio between the latent heat of evaporation and the heat of cohesion, v was found to be 2.17 × 1012.
