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
Evaporation of water emitted from soil surfaces is a key process of thehydrologic cycleand the surface energy balance. It can be limited by the solar energy to vaporize water, the amount of precipitation, the soil hydraulic properties and surface characteristics (albedo, roughness, and presence of...

xs = maximum humidity ratio of saturated air at the same temperature as the water surface (kg/kg) (kg H2O in kg Dry Air) x = humidity ratio air (kg/kg) (kg H2O in kg Dry Air) Note! The units for Θ don't match since the this is an empirical equation - a result of experi...
Controlling the dynamics of droplet evaporation is critical to numerous fundamental and industrial applications. The three main modes of evaporation so far reported on smooth surfaces are the constant contact radius (CCR), constant contact angle (CCA), a

whereQis the total Joule heating power,Ais the pore area, and ΔTis the temperature rise of the membrane.CΔTwas generally less than 5% ofQin the present study. Equation (1) assumes that the interfaces were flat during the experiment, which is a result of the low hydraulic pressure loss...
Dr. Abtew designed three types of lysimeter systems and performed evaporation and evapotranspiration measurements from open water, wetlands and receding water tables. He has developed and published an evapotranspiration model (Abtew equation, Simple Abtew Equation) that is being applied in South ...
PV=nRT, wherenis the number of moles. If we solve this equation forn/Vto calculate the number of moles per cubic meter, we can then convert this quantity to grams per cubic meter as requested. To do this, we need to use the molecular mass of water, which is given in the periodic ...
