1. A room in Universiti Malaysia Pahang, Pekan Campus contains atmospheric air at 30°C and 45% of temperature and relative humidity, respectively. Partial pressure of the dry air is 96 kPa with its standard specific heat of 1.005 kJ/kg K. Determine for this air its specific humidity (in kg H2O/kg dry air), and specific enthalpy (in kJ/kg dry air).

The air in a room is at 25 °C and a total pressure of 101.325 kPa . Air contains water vapor with a partial pressure of 1.76 kPa. a. Calculate the air humidity and relative humidity. b. Since you intend to use this air for drying fre sh fruits you plan to heat up the air to 50°C. Once you accomplish that, what would be the new relative humidity of the air if the moisture content is maintained? c. Intuitively...
