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 :
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...
u ut slatept I. 5. A dehumidifier is used to extract excess moisture from the air inside a room with dimensions 8x6x3 m3. The room was initially at a dry bulb temperature of 30°C, 70% relative humidity and ends up to a wet bulb temperature of 11°C, 100% relative humidity. If the dry air density is 1.2 kg/m3, what mass of water vapour has been removed by the dehumidifier?
The atmospheric air 32 °C dry bulb temperature and 70% relative humidity supplied to the cooling coil at a rate of 45m3/min. The air cooling to the saturated state and leaving at a temperature of 16 °C. Determine: a- Specific humidity at each state. b- Wet bulb and dew point temperatures at the final state c- Final relative humidity. d- Mass of water condensed. e- Rate of heat removed from the air in kW. f- Show the process on Psychrometric...
The humidity in a room at the temperature of 20°C is 40%. At the same time the humidity outside at the temperature of 0°C is 80%. In which direction do the water vapour molecules move - in the room or outside when the window is opened? Needed Information: 0°C = 0,61 Water vapor KPa 20°C = 2,34 Water vapor KPa I already solved the exercise, but I am afraid I haven't solved it correctly.....the teacher tends to get extremely irritated...
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)
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 520 m3 volume room
containing air at 27 ºC on a day where the relative humidity was
55%. (Vapor pressure at 27 ºC = 26.74 Torr)
3.Given that the air density at 0.987 bar and 27 ºC is 1,146
kg / m3, calculate the total moles of air and the total mass of the
air found in 400 m 3. Also determine the molar fraction and the
partial pressure of...
