Psychrometric Relationships and Equilibrium Moisture Content of Wood At Temperatures Above 212 F

Howard N. Rosen


Equations are derived to evaluate psychrometric relationships over a range of dry bulb temperatures from 200 to 500 F and wet bulb temperatures from 100 to 210 F. Wet bulb temperature, adiabatic saturation temperature, dew point, relative humidity, steam content, and enthalpy of humid air streams are discussed. Graphs and a chart are presented that relate relative humidities and dry and wet bulb temperatures to equilibrium moisture content of wood. The practical problems relevant to evaluation and usage of psychrometric-equilibrium moisture content interactions are discussed and several areas of future research are suggested.
