A numerical method is described by which the instantaneous evaporation rate from bare soil, regardless of its wetness, can be estimated from standard weather data and the physical characteristics of the soil profile. It is used to calculate potential evaporation from a surface energy balance without...
This contrasts with actual evaporation (AE), the rate of which is less than or equal to that of PE as it is dependant on the water available in the soil. Evaporation rates also depend on the type of land cover, but ‘short grass’ is often assumed as the standard. There are numerous...
I created a geometric body in SALOME. Its options (Parallelepiped): x = 0.2m, number of coordinates 20; y = 0.2m, coordinate number 20; z = 1m, number of coordinates 20; In the area of x and y i can arrange locate 6 coordinates. If more (10,18 coordinates) t...
The researchers have demonstrated the reason for the difference between the two models. In its simulations, their newly developed model shows reduced fractions of surface runoff and evaporation—and consequently, greater groundwater recharge. According to the new model, a farmer in the Mediterranean re...
hole itself. They are called quasinormal because they fade over time and their amplitude can be measured only for a small period. Such oscillations are usually described using frequency as a complex number, the real part of which is the periodic oscillations, and the imaginary—the decay rate....

H. Vahedi Tafreshi, E. Ercan& B. Pourdeyhimi 194Accesses 2Citations Explore all metrics Abstract In this note, the evaporation rate from a vertical wet fabric sheet is calculated using a free convection heat transfer correlation. Chilton–Colburn analogy is used to derive a mass transfer corr...
Calculating the Amount of Steam If we know the heat transfer rate - the amount of steam can be calculated: ms = P / he (4) where ms = mass of steam (kg/s) P = calculated heat transfer (kW) he = evaporation energy of the steam (kJ/kg) The evaporation energy at different steam ...
