air-water vapor mixture has a relative humidity of 40% and an enthalpy of 50 kJ/kg. What is the temperature (i.e., dry bulb temperature), wet bulb temperature, and humidity of the mixture? (Use the psychrometric chart, Figure 23.14)

Use the es value from the saturation vapor pressure question and a relative humidity of 0.8 to determine the actual vapor pressure, ea (include units). (The es value is 2kPa)

Moist air at 25 °C and 50% relative humidity enters a dehumidifier operating at stecady state with a volumetric flow rate of 280 m/min. The moist air passes over a cooling coil and water vapor condenses. Condensate exits the dehumidifier saturated at 10°C. Saturated moist air exits in a separate stream at the same temperature. There is no significant loss of energy by heat transfer to the surroundings and pressure remains constant at 1.013 bar. Determine (a) The mass flow rate of the dry air, in kg/min. ANA (b) The humidity ratios at the inlet and outlet using the psychrometric chart (Show the procedure on the attached chart).
