B) the psychrometric chart and air-conditioning processes we notice from the development in section a) that the equations relating relative and specific humidity, temperature (wet and dry bulb), pressure (air, vapor) and enthalpy are quite tedious and inconvenient. The wet-bulb temperature (wbt) is the temperature read by a thermometer covered in water-soaked cloth (wet-bulb thermometer) the precise relative humidity is determined by reading from a psychrometric chart of wet-bulb versus dry-bulb temperatures, or by calculation.
