A model is developed to define the evaporation rates of solutes from water. The rate equation, similar in form to the Knudsen equation, takes into consideration the effect of air and subwater turbulences on the
The rate of ideal evaporation, J, in a vacuum, as a function of temperature, is best described using the Langmuir equation:2 [8.1]J=Pv2πMRT where M is the molar mass of the evaporating species, R is the ideal gas constant, T the absolute temperature, and pv is the vapor pressure ...
In 1924 Hedestrand reported that the substrate surface effects greatly the rate of evaporation of water drops vanishing either in the Constant Contact Radius (CCR) or in the Constant Contact Angle (CCA) mode14. In the CCR mode the contact angle decreases during evaporation while the contact ...
Furthermore, we inferred that large and small molecules, which have different diffusion coefficients, can also be controlled by modifying the length and evaporation rate of the nanoslits. In particular, large molecules show slower diffusive transport than small ones. Therefore, shorter nanoslits are ...

neglecting diffusion along flow direction in favor of advection. Diffusion-dominant transport from porous surfaces provides an opportunity to establish a general boundary condition linking surface wetness with the evaporation rate through one simple expression combining the effects of both surface water ...
15, No. 4, 1990 Epn=[s(R-G)/L+ ap(v - vp)/ral/(s+ ap) (4) in which Epn is the Penman (1948) esti- mate of wet surface evaporation, v is the saturation vapour pressure at air temper- ature (T), s = dv/dT = rate of change of saturalion vapour pressure with respect ...
13.3.3Dependence of Evaporation Rate on Weather The dependence ofevaporation rateon weather can be explored using Eq.(13.27). It is clear from inspection of the equation that the rate of evaporation from water increases linearly with the absorption of net radiation and with the value of the atm...
