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...

1. (relative humidity) The partial pressure of water vapor in air is usually less than the equilibrium vapor pressure (or saturation pressure) at the ambient temperature; this is why a cup of water will spontaneously evaporate. The ratio of the partial pressure of water vapor to the equilibrium vapor pressure (at the same temperature) is called the relative humidity. Saturated air, at 100% relative humidity, would be in equilibrium with a cup of liquid water. The saturation pressure depends strongly...

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).
An air-water vapor mixture enters a heater-humidifier unit at 5°C, 100 kPa, 50% rh. The flow rate of dry air is 0.1 kg/s. Liquid water at 10°C is sprayed into the mixture al the rate of 0.0022 kg/s. The mixture leaves the unit at 30°C, 100 kPa. Calculate
