Atmospheric air having dry-bulb and wet-bulb temperatures of 33 and 29 degree c, respectively, enters a well-insulated chamber operating at steady slate and mixes with air entering with dry-bulb and wet-bulb temperatures of 16 and 12 degree c, respectively. the volumetric flow rate of the lower temperature stream is twice that of the other stream. a single mixed stream exits. determine for the exiting stream.
(a) the relative humidity.
(b) the temperature, in degreec.
pressure is uniform throughout at 1 atm. neglect kinetic and potential energy effects.
