Explanation:
According to the psychrometric chart at dry bulb temperature of and RH 70%, the absolute humidity = 0.011 kg/kg dry air
Formula to calculate humid volume is as follows.
dry air =
=
=
= 0.847 dry air
Hence, humid volume of air is 0.847 dry air.
Specific enthalpy of dry air = specific heat capacity of dry air × dry bulb temperature
=
= 21.126 kJ/kg dry air
Hence, the specific enthalpy of the air is 21.126 kJ/kg dry air.
As per the psychrometric chart at given conditions wet bulb temperature = 17.5
As per the psychrometric chart at given conditions dew point temperature = 15.5
