Exploring Psychrometric Principles

Using the psychrometric chart, Fig. A-9E, determine

(a) the dew point temperature corresponding to dry-bulb and wet-bulb temperatures of 80 and 70°F, respectively.

(b) the humidity ratio, the specific enthalpy of the mixture, in Btu per lb of dry air, and the wet-bulb temperature corresponding to a dry-bulb temperature of 80°F and 70% relative humidity.

(c) the relative humidity, humidity ratio, and mixture specific enthalpy corresponding to dry-bulb and wet-bulb temperatures of 80 and 65°F, respectively.

(d) Repeat parts (a)–(c) using Interactive Thermodynamics: IT.
