Humidity from Vapor Pressure. The air in a room is at 37.8°C and a total pressure of 101.3 kPa abs containing water vapor with a partial pressure pA = 3.59 kPa. Calculate:
Percentage and Relative Humidity. The air in a room has a humidity H of 0.021 kg H2O/kg dry air at 32.2°C and 101.3 kPa abs pressure. Calculate:
|A2:||Ans. (a) HP = 67.5%; (b) HR = 68.6%|
Use of the Humidity Chart. The air entering a dryer has a temperature of 65.6°C (150°F) and dew point of 15.6°C (60°F). Using the humidity chart, determine the actual humidity and percentage humidity. Calculate the humid volume ...
