The Penman formula for the evaporation rate from a lake is simplified to the following: E 0 = 700 T m / ( 100 A ) + 15 ( T T d ) ( 80 T ) ( mm day 1 ) where T m = T + 0.006h, h is the elevation (metres), T is th
It happens every day all around us, but not many people realize how much is involved with the evaporation of water into the atmosphere. In this lesson, we'll discuss the definition, formula, and calculations for evapotranspiration. What Is Evapotranspiration? One of the most remarkable life-gi...

The aquatic oxidation rate for acetyl acetone has been experimentally determined to be 9.9X10-9 L/mol-s at pH 6.4(7). Based on this rate and a hydroxyl radical concentration of 1X10-17 mol/L in water under continuous sunlight(8), the half-life for the aquatic oxidation of acetyl ...
Vapor-phase hexamethylene diamine is degraded in the atmosphere by reaction with photochemically-produced hydroxyl radicals(SRC); the half-life for this reaction in air is estimated to be about 6 hours(3,SRC). Abiotic Degradation: The rate constant for the vapor-phase reaction of hexamethylene ...
