NettetThe EPA Evaporation equation was developed to estimate evaporation from the … NettetThe Penman equation describes evaporation (E) from an open water surface, and was developed by Howard Penman in 1948. Penman's equation requires daily mean temperature , wind speed , air pressure , and solar radiation to predict E. Simpler Hydrometeorological equations continue to be used where obtaining such data is …

NettetPotential evaporation (PE) or potential evapotranspiration (PET) is defined as the amount of evaporation that would occur if a sufficient water source were available. If the actual evapotranspiration is considered the net result of atmospheric demand for moisture from a surface and the ability of the surface to supply moisture, then PET is a measure of the … NettetThe first formula in my question gives a result that is about 55% higher than the … piggly wiggly cookeville tn
