In below figure wet air at 30°C and 50% relative humidity enters a dehumidifier operating at steady state with a volumetric flow rate of 280 m3/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, (b) the rate at which water is condensed, in kg per kg of dry air flowing through the control volume. (c) the required refrigerating capacity, in tons. Schematic and Given Data: Cooling coil Heating coil ISaturated I mixture (AV), = 280 m³/min T, = 30°C 01= 50% 10°C Control volume Condensate, saturated at T, = 10°C

* Your answer is incorrect. A piston-cylinder assembly contains 0.7 lb of propane. The propane expands from an initial state where p₁ = 60 lbf/in.² and T₁ = 70°F to a final state where p₂ = 10 lbf/in.² During the process, the pressure and specific volume are related by pv² = constant.
