In an air conditioning plant, outdoor air mixes with recirculated air. Calculate the specific enthalpy, moisture content and dry-bulb temperature of the mixed air stream. Outdoor air:
Dry-bulb temp. = 5 C
Moisture content = 0.002
Mass flow = 2 kg/s
Recirculated air:
Dry-bulb temp. = 21 C
Moisture content = 0.012
Mass flow = 6 kg/s
