Air at 308C, 1 bar, 50% relative humidity enters an insulated chamber operating at steady state with a mass flow rate of 3 kg/min and mixes with a saturated moist air stream entering at 58C, 1 bar with a mass flow rate of 5 kg/min. A single mixed stream exits at 1 bar. Determine
(a) the relative humidity and temperature, in 8C, of the exiting stream.
(b) the rate of exergy destruction, in kW, for T0 5 208C.
Neglect kinetic and potential energy effects.
