High latent heat of vaporization:氢键使得液态水中的水分子很难以单一的分子形式(水蒸气)逃离整体(难被蒸发掉)。要让水从液态变成气态需需要100℃,这个温度比起其他液体要高很多。当水变成气态的时候,会需要吸取大量的能量,这就使得原本附着水的表面降温明显。流汗降温/叶子蒸腾就是这样一个道理,用来断开氢键的能...

Online calculator, figures and tables showing heat of vaporization of water, at temperatures from 0 - 370 °C (32 - 700 °F) - SI and Imperial units.
The embodiment of the utility model provides a recovery system of water and latent heat of vaporization in lignite flue gas, which comprises a boiler, a heater, a turbine, an air preheater, a dust collector and a chimney, wherein the heater is connected with the boiler and the turbine ...
Using confocal laser microscopy and micro-CT, we demonstrate that this unique structure ensures a steady supply of thin water layers, enhancing evaporation by minimizing latent heat at high temperatures. Additionally, the system initiates a self-cleaning process through bulk water convection when ...
This is known as the latent heat of vaporization, which at sea level is typically around 1,000 Btu/lb. So, cooling towers remove much heat from the recirculating water by a small amount of evaporation.An important concept for understanding cooling tower heat transfer is that of “wet bulb”...
[32], it was highlighted that the high surface tension of water requires a higher injection pressure to achieve sufficient atomization. The latent heat of vaporization is pressure dependent, resulting in a trade-off as injection into gases at higher pressure and thus temperature aids evaporation ...
where \(\Delta {h}_{vap}\) is the latent heat of vaporization of water under standard atmospheric pressure, \({C}_{p}\) is the specific heat capacity of water (4.2 kJ/kg K), and ΔT is the change of water temperature. Furthermore,\(\Delta {h}_{vap}\) is dependent on the ...
The phase transition between a gaseous state and a liquid state is directly associated with the latent heat of vaporization or condensation. Therefore, dehumidifiers involving a few steps, i.e., moisture absorption into absorbents, water collection, and regeneration of the absorbents, require high ...
