The air conditioning process in a humifidier, air at a dry bulb temperature of 30 ° C and RH of 15% increases the RH to 50%. Determine the amount of water vapor added in the humifidier per kg of dry air. (Kg water / kg air)

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).

HVAC UPVOTE WILL BE GIVEN. ANSWERS ARE GIVEN ALREADY. PLEASE WRITE THE COMPLETE SOLUTIONS. A room contains air at 20°c (Psat = 2.339 kPa) and 98 kPa at RH of 85%. Determine the following: a) Partial Pressure of dry air. (Ans. 96kPa) b) Specific Humidity of the air  (Ans. 0.013) c) Specific Enthalpy per unit mass of dry air (Ans.000 52.81)
