WebFinally, to calculate the amount of reheating necessary, we need to find the difference in enthalpy between the cooled air and the desired processing air conditions. From the psychrometric chart, we find that the enthalpy of the cooled air at 4°C and a specific humidity of 0.025 kg/kg dry air is approximately 8.1 kJ/kg. WebFor example, if the dry bulb temperature is 70°F and the wet-bulb temperature is 60°F, the enthalpy would be: Enthalpy (BTU/lb of dry air) = 0.24 * 70 + 60 = 66 BTU/lb of dry air.
