Air at 28 °C, 1 bar, 50% relative humidity enters an insulatedchamber operating at steady state with a mass flow rate of 5 kg/minand mixes with a saturated moist air stream entering at 4 °C, 1 barwith a mass flow rate of 8 kg/min. A single mixed stream exits at 1bar. Determine
(a) the relative humidity and temperature, in °C, of the exitingstream.
