Air at t1 = 24°c, p1 = 1 bar, 20% 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 . determine mass flow rate of the moist air entering at state 2, in kg/min.
