Exploring Psychrometric Principles

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

(a) the relative humidity, the humidity ratio, and the specific enthalpy of the mixture, in kJ per kg of dry air, corresponding to dry-bulb and wet-bulb temperatures of 30 and 25°C, respectively.

(b) the humidity ratio, mixture specific enthalpy, and wet-bulb temperature corresponding to a dry-bulb temperature of 30°C and 60% relative humidity.

(c) the dew point temperature corresponding to dry-bulb and wet-bulb temperatures of 30 and 20°C, respectively.

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