Comparison of Warm Water Evaporation Equations
Two methods of calculating the evaporation and, using the Bowen ratio, the sensible heat flux from warm water bodies are presented and their results compared. One method is empirical in that free convective and forced convective terms are simply added. The other method is a fluid mechanical approach combining the effects of free and forced convection in a nonlinear way by the use of the Monin-Obukhov similarity theory. The comparison of results depends on the value of roughness length. A specific roughness length allows the results of the two methods to compare within several percent.“
