Enthalpy is the measurement of energy in a thermodynamic system. The quantity of enthalpy is equal to the total content of heat (the system’s internal energy) plus the product of volume and pressure.  

Chuck Dewald III walks through how to evaluate this evaporative energy transfer process, employing metrics that evaluate how the energy transfer values can change as you apply drying efforts. 

This metric has been proven (through unbiased and third-party testing) to accurately evaluate evaporation of both free and bound water to within 0.5-1.0% accuracy, evaluate the point of visible condensation to within 0.6% accuracy, and ultimately predict ALL energy components of the psychrometric chart to within 0.6-0.72% accuracy.
