Vapor Pressure and Evaporation Coefficient of Glycerol
نویسندگان
چکیده
Measurements of the vapor pressure in the range 291 to 341 K and of the evaporation coefficient of liquid glycerol are reported. In contrast to the results of other authors a unit evaporation coeff lcient is found. The higher vapor pressures given by several other authors are shown to be due to minute traces of water. Using our low temperature data and the data of reliable investigations at higher temperatures the following vapor pressure equation for liquid glycerol was obtained by a least-squares treatment: log p/Torr = 41.98405 6024.479/T/K -10.3272 log T/K.

A More Accurate Prediction of Liquid Evaporation Flux
In this work, a more accurate prediction of liquid evaporation flux has been achieved. The statistical rate theory approach, which is recently introduced by Ward and Fang and exact estimation of vapor pressure in the layer adjacent to the liquid–vapor interface have been used for prediction of this flux. Firstly, the existence of an equilibrium layer adjacent to the liquid-vapor interface ...

The evaporation heat transfer and pressure drop characteristics of HFC-161 in a horizontal smooth tube with an inside diameter of 9 mm was experimentally investigated. The local heat transfer coefficient and total pressure drop were measured at the heat flux ranging from 15 – 25 kW/m, the mass flux ranging from 100 – 200 kg/(m·s), and the evaporation temperature of 5, 10 °C. The experimental re...

متن کاملAn extremum principle of evaporation
[1] It is proposed, on the basis of an argument of thermodynamic equilibrium, that land-atmosphere interactive processes lead to thermal and hydrologic states of the land surface that maximize evaporation in a given meteorological environment. The extremum principle leads to general equations linking surface energy fluxes to surface temperature and soil moisture. The hypothesis of maximum evapo...
متن کاملDynamics of Water Vapor Content around Isolated Sprinklers: Description and Validation of Model
Irrigation consumes considerable water to satisfy the current food demand. An improvement in water use efficiency for irrigation is essential. Wind drift and evaporation losses reduce the water use efficiency of center pivot irrigation systems in arid and semi-arid areas. In this paper, a model of water vapor dynamics during and after overhead sprinkler irrigation was developed and validated by...
