A large room contains moist air at 30 °C, 102 kPa. The partial pressure of water vapor is 1.5
kPa. The mixture is cooled at constant volume until its temperature is reduced to 10 °C.
Determine
a) The relative humidity.
b) The initial humidity ratio, in kg (vapor) per kg (dry air).
c) The dew point temperature, in °C.
d) The temperature at which condensation actually begins, in °C.
e) The amount of water condensed, in kg, if the mass of the initial water vapor is 10kg.
