Air at t1 = 24°c, p1 = 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 t2 = 7°c, p2 = 1 bar. a single mixed stream exits at t3 = 17°c, p3 = 1 bar. neglect kinetic and potential energy effects.
1. determine the rate of entropy production, in kj/min. k.
