Evaluating Humidity At Dry Bulb Temperatures Above The Normal Boiling Point of Water A Research Note
Keywords:
Wet bulb temperature, dry bulb temperature, relative humidity, adiabatic saturation temperatureAbstract
Several methods were compared for evaluating relative humidities at temperatures between 210 and 300 F from psychrometric relations. An explicit method of calculating relative humidity, assuming that the wet bulb temperature is equivalent to the adiabatic saturation temperature, is shown to predict relative humidities with a maximum deviation of only 1% from those values predicted by more theoretically rigorous equations.References
