Using the psychrometric chart, calculate the following:
1. The absolute humidity of air that has RH=40% and a dry bulb temperature 60oC.
2. The wet bulb temperature under these conditions.
3. The RH of air having a wet bulb temperature 44oC and a dry bulb
Temperature 70oC.
4. The dew point of air cooled adiabatically from RH 30% and a dry bulb
Temperature 50oC.
5. The change in RH of air with a wet bulb temperature 38oC, heated from 50oC to
86oC (dry bulb temperatures).
