25. Homework: Twenty liters of air at 20°C and a relative humidity of 60% are compressed isothermally to a volume of 4 liters. Calculate the mass of water condensed. The saturation vapor pressure of water at 20°C is 23 hPa. Density of air at 0°C and 1000 hPa is 1.28 kg/m3.
calculate the mass of water vapor present in a room of 400 m ^ 3 volume containing air at 27 ° C on a day where the relative humidity was 60% (vapor pressure at 27 ° C = 26.74Torr)
On a particular day the room temperature was 300 C and the dew point was observed to be 200 C, and the relative humidity was 80%. With the aid of an air conditioner if a part of the water vapor was removed, and then the relative humidity was 40% and the temperature was 200 C. Suddenly if the due to a power failure the Air conditioner stops working and the temperature rises to 300 C. If no water vapor could...
A room contains air at 20 C and a total pressure of 95 kPa with a relative humidity of 40 percent. The gas constant for air is 0.287 kJ/(kg-K). The mass of dry air in the room is 30 kg. What is the volume of the room in m3 :
